Consider the two logical expressions: (p ∨ q) ∧ ¬p and ¬p ∧ q. Determine which of the following is correct:
Statement-1: The two expressions are logically equivalent.
Statement-2: The final columns of their truth tables match exactly.
- Statement-1 is false, Statement-2 is true.
- Statement-1 is true, Statement-2 is true; Statement-2 correctly explains Statement-1.
- Statement-1 is true, Statement-2 is true; Statement-2 does not correctly explain Statement-1.
- Statement-1 is true, Statement-2 is false.
Correct answer: Statement-1 is true, Statement-2 is true; Statement-2 correctly explains Statement-1.
Solution
Both logical expressions yield the same truth values under all possible interpretations of p and q, confirming their logical equivalence. Since the truth tables for both expressions match exactly, Statement-2 accurately supports Statement-1.
