Math Problem Statement
Let P: (¬(p ∧ q) ⇒ p) and Q: (¬p ∨ ¬q) ⇒ p. Which of the following statement is correct about P and Q? 1) P and Q are equivalent. 2) P and Q are not equivalent.
Solution
The question asks to determine whether the two logical statements and are equivalent. Let us carefully analyze the problem.
Statements:
Step-by-Step Solution:
Step 1: Rewrite
The statement :
- can be rewritten using De Morgan's law as .
- Thus, simplifies to:
Step 2: Compare and
The rewritten form of is identical to the given : Since both and are the same expression, they are logically equivalent.
Final Answer:
P and Q are equivalent.
