In the given question we are told that we have three propositions p, q and r, and the truth values of these propositions are already given to us.
00:10
We are told that p is false, q is true and r is false.
00:15
Now, we have been given a statement in the question in the symbolic form and we have to figure out the truth value of this statement.
00:25
So, what is given to us in this question is, not p, or not or not, q and r.
00:44
So this is the statement that we have been given in the question.
00:49
So what we could do first is figure out, let's start from the statements that we have inside this bracket, right? so the proposition q has a truth value of true and the proposition r has a truth value of false.
01:08
So we should know that the and symbol, the statement, or let's write the and symbol, the statements having and symbol, the statements having and symbol, symbol and symbol of the form of the form x and y is true only when is true only when both the statements x and y are true are true so over here we can clearly see that one statement is having a truth value of true and the other statement is having a truth value of false.
02:02
So we can write q and r is having a truth value of false...
