Question
If p
is False and q
is True, what is the truth value of
~p <--> ~q
Group of answer choices
- True
- False
Solution
The truth value of ~p <--> ~q when p is False and q is True is False. Here's why:
-
The symbol ~ is a negation operator. It flips the truth value of the statement that follows it. So, ~p is the negation of p, and ~q is the negation of q.
-
Given that p is False, ~p (the negation of p) is True.
-
Given that q is True, ~q (the negation of q) is False.
-
The symbol <--> is a biconditional operator. It returns True if both the statements on its left and right have the same truth value, and False otherwise.
-
So, ~p <--> ~q is True <--> False, which is False because True and False do not have the same truth value.
