[0:04]In this lesson number three, we are going to solve five different question on the topic syllogism and all the five different question, the conclusion that is going to be based on possibility.
[0:14]So possibility can also be called as can be or otherwise question mark. So friends, listen carefully. In lesson number one, we have seen some of the conclusion that is based on some and all.
[0:24]And lesson number two, we have again solved five different question and all the five different question where the conclusion that is based on no. So in this lesson number three, we are going to solve five different question and all the five different question, where the conclusion that is going to be based on possibility.
[0:40]So friends, listen carefully. Lesson number three and lesson number two, always you need to compare both the lessons because lesson number two opposite is lesson number three.
[0:50]So friends, listen here. In lesson number two, what we did is, if we find a no conclusion, we used to draw basic diagram, and we used to draw possible diagram.
[0:59]And if it is false in any one diagram, according to no conclusion, we used to say it is false. Right? So friends, listen, in lesson number two, I have clearly told that if it is false in any one diagram, then no conclusion is false.
[1:13]But according to lesson number three, if it is true in any one diagram, possibility is true. That is the difference between possibility and no.
[1:23]So friends, listen the concept carefully. If it is false in any one diagram, no conclusion is false.
[1:33]If it is true in any one diagram, possibility is true. If it is true in both the diagram, so possibility is true.
[1:38]If it is false in both the diagram, where possibility is false. So friends, which is most important.
[1:45]So listen carefully, when we go for no conclusion, if it is false in any one diagram, then the answer is false.
[1:52]But when we move on to possibility conclusion or can be conclusion or question mark conclusion, so if it is true in any one diagram, then the answer is true.
[2:02]So if it is true in both the diagram, again possibility is true. When it is false in both the diagram, then possibility is false.
[2:08]And another important thing, while solving lesson number two, I have told you one note, that second note. If all the parameters are inside a single Venn diagram.
[2:18]So friends, listen carefully. I assuming that A, B, C, D. Right? So assume there is a some question and we have drawn the Venn diagram for that question.
[2:26]If all the parameters are inside a single Venn diagram, according to lesson number two, I have told that no conclusion is always wrong.
[2:35]In this lesson number three, if all the parameters are inside a single Venn diagram, possibility is always true. So friends, listen carefully, which is most important.
[2:46]If all the parameters are inside a single Venn diagram, no conclusion is false. If all the parameters are inside a single Venn diagram, possibility conclusion is true.
[2:55]So lesson number two opposite is lesson number three. So let me move on to all the five different question so that you can able to understand the concept of possibility clearly.
[3:04]So before going for the question, so first of all, you should know how to draw the possible diagram, that is important. Because some students will think that this possible diagram is correct or this possible diagram is wrong.
[3:15]So they don't know how to draw the possible diagram. So first of all, let me see a possible diagram for a question, then we can move on to all the various question that is based on possible conclusion.
[3:25]Now we can learn how to draw the possible diagram for this statement. Right? So let me move on to the simple question.
[3:31]So friends, listen here, some tree or paper, all papers are car and no car is truck.
[3:37]So let me draw the Venn diagram for the given statement, right? So some papers, some tree are paper. So some tree are paper.
[3:45]And all papers are car. And the last statement is no car is truck.
[3:50]So friends, this diagram which we used to call it as a basic diagram. So what are all the possible diagram that we can draw by using this statement.
[3:58]So friends, listen here, I can this is a basic diagram, right? So this will be the basic. So let me move on to all the possible diagram, friends. So possible diagram is, I can draw like this, because they have in the statement, they have clearly told that they should not be any connection between car and truck.
[4:13]But we can connect the truck to the tree, right? So this is one possible diagram. So I can draw truck here, and I can draw tree here, and also this can be a paper and this can be a car.
[4:27]So this can be one possible diagram. So friends, always remember that you can draw whatever diagram by using the statement, but you should not violate the statement, that is important.
[4:39]So after drawing this possible diagram, check the statement whether you have drawn the diagram correctly. Some tree are paper. Some tree are paper, all papers are car. All papers are car and no car is truck. There is no link between car and truck.
[4:52]So according to the statement, we have drawn the diagram, so which we used to call it as a possible diagram. This will be the basic diagram and this is the possible diagram. So we have not violated the statement.
[5:01]So we can say that it is one of the possible diagram. So let me move on to the second possible diagram, friends. You can draw various types of possible diagram, but remember that every time while drawing a diagram, you should not violate the statement, that is important.
[5:13]Right? So this can be drawn as a tree, truck, a pen. Sorry, it's a paper, right? So paper and car. So friends, this can be also called as an another possible diagram.
[5:30]So listen here, some tree are paper. So some tree are paper, all papers are car. All papers are car and no car is truck. There is no link between car and truck.
[5:39]So we can say that this is one of the possible diagram. And some students say this is one of the possible diagram. Listen here, friends. Most of the students will make a mistake.
[5:54]They used to draw like this, tree, and paper, and car, and they used to draw like this, and this is truck, right? And they used to say this is one of the possible diagram.
[6:07]Whether this is possible, this possible diagram is correct or wrong? Exactly wrong, this is not the possible diagram for the given statement. Why because some tree are paper, statement number one satisfies.
[6:17]All papers are car, all papers are car, statement number two satisfy. But when we see statement number three, no car is stuck. They should not be any connection between car and truck.
[6:27]But according to the possible diagram that we drawn, here all cars are truck. But the statement is no car is truck. We have violated the statement, so this is not the possible diagram.
[6:37]You can draw diagram as per your wish, you can draw car here, you can draw paper here, so everything is your wish in the possible diagram.
[6:45]But remember that whatever diagram that you are going to draw, you should not violate the statement, that is important. So let me move on to all the five question that is based on this possibility case.
[6:54]Question number one. So the statements are some papers are pen. So some papers are pen.
[7:03]And the second statement is all pen are scale. So all pen are scale. And the last statement is no scale is a marker.
[7:11]So the meaning is there is no connection between scale and a marker. So friends, finally, we have drawn the Venn diagram for the given statements.
[7:18]So let me move on to conclusion number one. So some marker being paper is a possibility. So the conclusion that is based on possibility.
[7:26]So friends, if the conclusion that is based on possibility, you need to draw the basic diagram and you need to draw the possible diagram. If it satisfies in any one diagram, then the answer is correct.
[7:37]So let me move on to conclusion number one, friends. Some marker being paper is a possibility. So this is the basic diagram.
[7:44]So according to the basic diagram, there is no connection between paper and a marker, right? But they are saying that some marker being paper, right?
[7:51]So according to the basic diagram, paper, there is no link between marker and paper, so according to the basic diagram, the conclusion is wrong.
[8:00]When we move on to the possible diagram, and according to the statement, they have clearly told that no scale is a marker.
[8:05]There is no connection between scale and marker. But we can connect this marker with the paper. There is a possible of connecting marker with the paper.
[8:15]So when we connect marker with the paper, it satisfies the conclusion. Some marker being paper is a possibility.
[8:20]And here, some marker being paper is a possibility. So we can say that in a possible diagram, the conclusion follows.
[8:28]If it is true in any one diagram, then the answer is true. So finally, we can say that conclusion number one is true.
[8:43]So friends, listen carefully. No scale is marker, but we can connect the marker to with the paper, right? And when we connect the marker with the paper, it satisfies the conclusion.
[8:52]Some marker being paper is a possibility. So once whenever you draw a diagram, you should not violate the statement, that is important.
[8:59]So if if some students will think whether this diagram is correct or not. If you think like that, just read the statement again. Some paper are pen.
[9:09]So some paper are pen, statement number one is correct. Statement number two, all pen are scale. So all pen are scale. Statement number three, no scale is a marker.
[9:17]No scale is a marker, there is no connection between scale and marker. So the possible diagram is correct and it satisfies the conclusion. So we can say that conclusion number one is true.
[9:25]So let me move on to conclusion number two.
[9:30]Okay. So friends, conclusion number two. All marker being paper is a possibility.
[9:35]So friends, listen here, all marker being paper is a possibility. And I am drawing marker here. So all marker being paper is a possibility.
[10:25]So we can say that according to possible diagram, conclusion follows. After drawing the possible diagram, if you want you need to check with the statement whether the diagram is correct or not.
[10:32]Just read the statement again, some paper are pen, some paper are pen, all pen are scale. So all pen are scale and no scale is marker. There is no connection between scale and marker.
[10:41]So according to the statement, the diagram that we drawn is correct. And also all markers being paper is a possibility, it satisfies the conclusion.
[10:50]So we can say that conclusion number two follows. So for this question the answer is conclusion number one and conclusion number two is true.
[10:57]Question number two. And the statement number one is, some tree are paper. So some tree are paper.
[11:05]And the second statement is some papers are pen. So some paper are pen, all pens are car.
[11:13]So all pen are car. And the last statement is all cars are truck. And the last is no truck is cycle. So the meaning of no truck is cycle, there is no connection between truck and cycle.
[11:22]So let me draw cycle here. So this line indicates that there is no connection between truck and cycle.
[11:29]So friends, finally, we have drawn the Venn diagram for the given statement, right? So let me move on to conclusion number one.
[11:35]So all cycles being paper is a possibility. So the conclusion that is based on possibility, right? So all cycles being paper.
[11:43]So friends, according to the basic diagram, there is no connection between paper and a cycle. So it does not satisfy the conclusion.
[11:50]So we can say that according to basic diagram, conclusion number one is false. When we move on to the possible diagram, all cycles being paper is a possible.
[11:59]We need to check whether this is possible or not. So friends, listen carefully, according to the statement, they have clearly told that no truck is cycle.
[12:07]There is no connection between truck and cycle. But there is a possible of connecting cycle with paper. And there is a possible of connecting cycle with tree. I can draw cycle here.
[12:17]This is also one possible, if I draw cycle here, just read the conclusion again, all cycle being paper is a possibility.
[12:23]It's correct or not? So we can say that this possible diagram, we can surely say that conclusion follows. If it is true in any one diagram, then the answer is true.
[12:33]So we can say that conclusion number one is true. Some students will think whether this diagram is correct or not.
[12:38]If you think like that, just, so we have drawn a possible diagram like this, right? And it satisfies all cycle being paper is a possibility, it satisfies.
[12:47]If you think whether this diagram is correct or not. Just read the statement again and check whether we have violated the statement or not. Statement number one, some tree are paper.
[12:55]Some tree are paper, statement number two, some papers are pen, some paper are pen, statement number three, all pen are car, all pen are car.
[13:04]And statement number four, all car are truck, and the last statement, no truck is cycle. There is no connection between truck and cycle in the possible diagram, which is correct.
[13:12]So we have not violated the statement and the possible diagram is correct and also it satisfies the conclusion. So finally, we can say that conclusion number one is true.
[13:22]So let me move on to second conclusion.
[13:30]Okay. So conclusion number two. Some tree being cycle is a possible. So some tree being cycle is definitely possible.
[13:35]Look at here friends, in the basic diagram, there is no connection between tree and cycle. So according to basic diagram, conclusion two is false. So when we move on to the possible diagram, there is a possible of drawing a cycle like this.
[13:46]Right? So when we draw a cycle like this, this region we can say that some tree are cycle. And the conclusion says some tree being cycle is a possible.
[13:55]So we can definitely say that some tree being cycle is a possible. So in the possible diagram it satisfies, if it is true in any one diagram, then the conclusion is true.
[14:04]So we can say that conclusion number two is true. So let me move on to conclusion number three.
[14:14]Okay. Conclusion number three. Some cycle being car is a possibility. Friends, the conclusion number three is most important conclusion.
[14:22]Listen carefully, some cycle being car is a possibility. So friends, when the according to the basic diagram, there is no connection between cycle and car.
[14:30]But the conclusion says some cycle being car. So according to basic diagram, where conclusion does not follows, that is conclusion is false. When we move on to the possible diagram, there is no possible of connecting cycle with car.
[14:42]Because we already know that no truck is cycle. We should not connect truck and cycle. So where car, pen, all are inside the truck. So there is no possible of connecting cycle with car.
[14:50]And the conclusion says some cycle being car. It is definitely not possible. There is no possible of connecting some cycle are car.
[15:00]So in the possible diagram also it is false. So if it is false in both the diagram, then the answer is false.
[15:08]So friends, can you able to understand this concept? We can connect the cycle with paper. We can connect cycle with tree, but there is no possible of connecting cycle with truck. And there is no possible of connecting cycle with car, and also there is no possible of connecting cycle with pen.
[15:22]So according to the possible diagram also there is no possible of connecting car and the cycle. So in possible diagram it is false.
[15:28]And basic diagram it is false. If it is false in both the diagram, then the answer is false. So let me move on to the last conclusion. So the last conclusion is all cycle being pen is a possibility.
[15:40]Again all cycle being pen is definitely not possible. We know that there is no connection between cycle and pen in the basic diagram.
[15:47]So it does not satisfy the conclusion. When we move on to the possible diagram, there is no possible of connecting cycle and pen.
[15:54]But the conclusion says all cycle being pen. That is also not possible. In both the diagram, where the conclusion is false. So we can say that conclusion number four is false.
[16:03]So friends, listen carefully. So finally, we got an answer that is conclusion number one and conclusion number two is true.
[16:09]Question number three. So the statement number one is all cakes are sweet. So all cake are sweet.
[16:18]And the second statement is no sweet is chocolate. So no sweet is chocolate. Okay.
[16:26]So there is no connection between sweet and chocolate, right? So all sweets are good. And the last statement is some goods are best.
[16:42]So some goods are best. So friends, finally, we have drawn the Venn diagram for the given statement. So let me move on to conclusion number one.
[16:50]So conclusion number one is all chocolates being best is a possibility. So here it is chocolate and here it is best.
[16:58]So according to the basic diagram, there is no connection between chocolate and best, so according to basic diagram, we can say that conclusion is false.
[17:06]But when we move on to the possible diagram, all chocolates being best is a possibility. So friends, listen carefully, we can draw chocolate here, right?
[17:15]So when we draw chocolate here, all chocolates being best is a possibility. And we have not violated the statement. Why because read the statement again.
[17:22]All cakes are sweet. And no sweet is chocolate, so there is no link between sweet and chocolate. And the next is all sweets are good and some goods are best.
[17:32]So friends, we have not violated the statement and it satisfies the conclusion because all chocolates being best is a possibility.
[17:39]So when the possible diagram, where conclusion is true. So if it is true in any one diagram, then the answer is true. So finally, we can say that conclusion number one is true.
[17:48]So let me move on to conclusion number two.
[18:34]Okay. So just check whether we have drawn the diagram correctly or not, right? So all cakes are sweet. So all cakes are sweet, all sweets are good. All sweets are good. And no sweet is chocolate, no sweet is chocolate. There is no connection between sweet and chocolate.
[18:48]And the last statement is some goods are best. So friends, we have not violated the statement and it satisfies the conclusion.
[18:55]The conclusion is all chocolates being good is a possibility. All chocolates being good is a possibility. So we have not violated the statement and it satisfies the conclusion.
[19:05]So we can say that in the possible diagram, where conclusion follows. If it is true in any one diagram, then the answer is true. So finally, we can say that conclusion number two is true.
[19:15]Okay. So let me move on to conclusion number three.
[19:25]Okay. Conclusion number three is all goods being chocolate is a possibility. So friends, all goods being chocolate is a possible.
[19:33]So according to basic diagram, there is no connection between good and chocolate. So according to basic diagram, where the conclusion is false. When we move on to the possible diagram, listen carefully.
[19:42]They have clearly told that there is no connection between sweet and chocolate. But when we draw a possible diagram like this, then all sweet becomes chocolate.
[20:14]So there is no possible of drawing all goods are chocolate. So in the possible diagram also it is false. So if it is false in both the diagram, then the answer is false.
[20:24]So friends, listen carefully. All chocolates being good is a possible. But all goods being chocolate is not at all possible. Friends, can you able to understand this concept?
[20:31]One of the most important concept. We can draw chocolate here. If we draw chocolate here, all chocolates being good is a possibility.
[20:39]But if you need to satisfy all goods being chocolate is a possible. So only chances is to draw the diagram like this. When we draw chocolate like this, there will be a connection between sweet and a chocolate.
[20:50]And in the statement itself, they have clearly told that they should not be any connection between sweet and chocolate. So finally, we can say that all goods being chocolate is not at all possible.
[21:02]So in the possible diagram also it is false. So if it is false in both the diagram, then the answer is false. So friends, listen carefully.
[21:54]So finally, we got an answer that is conclusion number one and conclusion number two is true. Question number four.
[22:36]So some blue are green, right? So some blue are green. And the second statement is some green are pink.
[22:44]So some green are pink. And the third statement is all pink are yellow. So all pink are yellow.
[22:54]And next is no yellow is black and some black are red. So no yellow is black, right? So we can draw black here. So no yellow is black and some blacks are red.
[23:04]So friends, finally, we have drawn the Venn diagram for the given statement. So friends, listen here. They have clearly told that there is no connection between yellow and black, right?
[23:13]So friends, after drawing this diagram, just analyze it, right? What are all the possible diagram that we can draw.
[23:20]So friends, listen here. There is no connection between black and yellow, but there is a possible of connecting black with green and there is a possible of connecting black with blue.
[23:32]And the second is there is a possible of connecting red with yellow. There is a possible of connecting red with pink. There is a possible of connecting red with green and there is a possible of connecting red with blue.
[23:42]So friends, let me move on to the conclusion. So conclusion number one. Some red being yellow is a possibility. So it's based on possibility conclusion, so you need to draw the basic and a possible diagram, right?
[23:54]So some red being yellow. So friends, here it is red and here it is yellow. So there is no link between red and yellow. So the basic diagram conclusion does not follows.
[24:04]Let me move on to the possible diagram. So friends, some red being yellow is a possible. I think when we draw red like this.
[24:12]Listen carefully, friends. So when we draw red like this, then we can surely say that some red being yellow is a possibility.
[24:20]And we have not violated the statement because read the statement again. Some blue are green and some green are pink, all pink are yellow, and no yellow is black.
[24:30]There should not be any link between yellow and black. So in this diagram, there is no link between yellow and black and some blacks are red.
[24:36]So we can definitely say that we have not violated the statement and it satisfies the conclusion. So some red being yellow is a possibility.
[24:44]So in the possible diagram, conclusion one satisfies. So if it is satisfies in any one diagram, then the answer is true. So conclusion number one is true.
[24:53]So let me move on to conclusion number two.
[25:05]Okay. So friends, conclusion number two is all red being blue is a possible. So all red being blue is definitely possible.
[25:12]Why because we can draw like this. Listen here, friends, the conclusion says all red being blue is a possible. So if in the basic diagram, there is no connection between red and blue.
[25:22]So we can say that according to basic diagram, where the conclusion does not follows. But when we move on to the possible diagram, we can draw like this, right?
[25:30]So this can be red and this can be black. So this is also one possible diagram. Listen carefully, friends.
[25:39]So I am saying that this is one of the possible diagram. Just read the statement again whether we have violated the statement or not. Some blue are green.
[25:44]Some green are pink, all pink are yellow. And no yellow is black. There should not be any link between yellow and black. So in this diagram, there is no link between yellow and black.
[25:56]And some blacks are red. So we have not violated the statement, so the diagram is a possible diagram. So in this diagram, the conclusion says all red being blue is a possible.
[26:04]So in this diagram, all red being blue is a possible. So in the possible diagram, where the conclusion is true. So if it is true in any one diagram, then the answer is true.
[26:14]So finally, we can say that for this question number four, the answer is conclusion number one is true and conclusion number two is true.
[26:22]So friends, listen carefully. You should be strong on the concept and you should practice more number of question. Nearly 50 to 60 question.
[26:30]So if you practice more than 50 or 60 question that is only based on possibility, you will definitely crack all the question is based on possibility.
[26:38]So friends, let me move on to the last question that is fifth question. I think fifth question, we are going to apply the second rule.
[26:45]I think in the initial stage of a video itself I have told you, right? If all the parameters are inside a single Venn diagram, possibility always follows.
[26:55]So friends, let me move on to question number five. The last fifth question. So some papers are switch.
[27:00]So some paper or switch. And the second is some switch are book. So some switch are book and all books are note.
[27:09]So all book are note, then all note are pen. So all note are pen and some pens are scale. So some pens are scale.
[27:19]So friends, finally, we have drawn the Venn diagram for the given statement. So friends, listen carefully.
[27:24]Here, paper, switch, book, note, pen and scale. So all the parameters are inside a single Venn diagram.
[27:32]We can say that here all the parameters are inside a single Venn diagram. If all the parameters are inside a single Venn diagram, if you find any conclusion that is based on possibility, it is always true.
[27:44]Listen here, friends. The conclusion number one. Some papers are scale is a possibility. So some papers are scale. So all are inside a single Venn diagram, possibility follows.
[27:56]Don't check whether it is a basic diagram, possible diagram, true or false. If it is in a single Venn diagram, always possibility is true. Conclusion number two.
[28:04]Some paper being note, some paper being note, again it is possible. So friends, listen carefully.
[28:10]There is a small difference between lesson number two and lesson number three. In lesson number two, that is based on no conclusion.
[28:18]If all the parameters are inside a single Venn diagram, no conclusion is false. If all the parameters are inside a single Venn diagram, possibility conclusion is true.
[28:27]That is the difference between lesson number two and lesson number three. So friends, finally, in this lesson number three, we have solved five different question on the topic syllogism, the conclusion that is based on possibility.
[28:40]So friends, after watching lesson number one, lesson number two, lesson number three, take your books and practice many question that is based on possibility and practice more number of question that is based on no, some and all.
[28:51]So after practicing all these conclusion, then go and watch lesson number four, that is based on some not conclusion. So friends, thank you so much for watching this video.
[29:01]If you really like this, share this to your friends, those who are preparing for a competitive exam, so that the videos will be so helpful for them. So thank you so much for watching this video. Bye.
