Question 3 [3 points] Give a counterexample to show the following form is invalid. P or Q P and Q



Answers

Which of the following is a contradiction? (1) $(\mathrm{p} \vee \mathrm{q}) \Leftrightarrow(\mathrm{p} \wedge \mathrm{q})$ (2) $(\mathrm{p} \vee \mathrm{q}) \Rightarrow(\mathrm{p} \wedge \mathrm{q})$ (3) $(p \Rightarrow q) \vee(q \Rightarrow p)$ $(4)(\sim q) \wedge(p \wedge q)$

So here we are given for conditions that is peace true and Q is true, then P is false and Q is too then he is true and curious waltz and then off the table. And we are given a by conditional statement that is be the final leaf cute. And we need to check in which of these following conditions. This given by conditional by conditional statement is true. Okay? So in order to or if my conditional statement to be true then both P and Q should be equal. That is hey the beat he should be true and you should be true or P should be false and key should be force. Then only B. E. Finally ask you is true or false. That is the government conditions exist. This by condition exists. So in this case this will not work because both are different here also do not work. So here about that group. Therefore this is a conditional statement and dissatisfied the given condition.

Obviously last night, the negation of our statement. And let's let P be if you are not part of the solution and then Q b, you're part of the problem. So we have a delegation of our conditional is equivalent to pee. And the negation cute carpi is you're not part of the solution, and then we Howard connective ends and then que ordination of Q, which is you are not part of the problem.

In the question we are given to statements Thank you. And we must check. Are there to our faults here? The statement B is every reflexive. Yeah. Yeah relation. Okay. Yes, symmetric. So let's take an example let's set A. B. Hey come on baby. And the relation on set A. That will be a comma. A become a B. I be comma. So let's take if the relation is reflexive since A. Is related to A. And B is related to be uh for all the elements in the relation is reflects it. And let's check if it's symmetric yet we have be related to A but we don't have a related to be so it's not symmetric. So a statement piece false. And let's check statement Q. Every and I symmetric relation. Yes, reflexive. So let's consider another relation on set. That will be a comma A and B comma. Okay so here uh let's take of its anti Semitic here we have become A but we don't have a car maybe. So it's anti symmetric. Here. We have a camera and a camera, and a. Is equal to a. Soy is anti symmetric. And let's check fits reflexive. Uh We have a related to air, but we don't have to be related to be, so it's not uh a reflection, so Q. Is also false, so it's either P. Or Q. Thank you.

Hey, it's clear sailing name right here. So two propositions are logically equivalent if they have the same truth value for any combination of truth values for the variables. P. Q. R. So here were introduced the new kind of symbol. So this symbol, the Down Arrow is nor soapy, nor Q is true if both p and Q r falls. So let's make a true table for a pee. Q. Peor que? Not he or Q groupie nor. Q. So we have True True Falls Falls Q. Is true false? True Falls Pee or Q has to be true. True, true, false, since it's one or the other, and not pee or cute is false. Falls falls true and P nor. Q. This is the downer of the North sign is true. If both p and tour falls, so has to be falls for the 1st 1 Second, one and third, and the last one is true Soapy nor Q is logically equivalent with not pee or Q, because the last two columns of the falling truth table or identical, with the exception of the compound propositions in the first room
