In a truth table, if p is true and q is false, which of the following notations is false
The correct answer is: C
Explanation
p | p | p ⇒ q | (p ⇒ q) ∧ q | [(p ⇒ q) ∧ q] ⇒ q | [(p ⇒ q) ∧ q] ⇔ q | [(p ⇒ q) ∧ q] ∧ q |
[(p ⇒ q) ∧ q] ∨ ∼ q |
T | F | F | F | T | T | F | T |
From the truth table above, [(p ⇒ q) ∧ q] ∧ q is FALSE.
