Question
Suppose that Pand Q are statements for which P→Q is false. What conclusions (if any) can be made about the truth value of each of the following statements? Briefly explain work.
(a) Q
(b) P↔Q (recall: P↔Q≡ (P→Q)∧(Q→P))
(c) ¬P→Q
Expert Solution
Step 1
Truth table for is:
P | Q | |
T | T | T |
T | F | F |
F | T | T |
F | F | T |
In case is false, which means P is True and Q is False.
If P is true and Q is false, then is False.
is False if P is True.
Now , is False and Q is also False , so is True.
