The correct Answer is:
To find the inverse of the statement "P implies ~Q", we can follow these steps: ### Step 1: Understand the implication The statement "P implies ~Q" can be written in logical notation as: \[ P \implies \neg Q \] ### Step 2: Apply the inverse rule The general rule for finding the inverse of an implication \( A \implies B \) is: \[ \neg A \implies \neg B \] Here, \( A \) is \( P \) and \( B \) is \( \neg Q \). ### Step 3: Negate both parts Using the inverse rule, we negate both parts: - Negate \( A \) (which is \( P \)): This gives us \( \neg P \). - Negate \( B \) (which is \( \neg Q \)): The negation of \( \neg Q \) is \( Q \) (since negating a negation gives the original statement). ### Step 4: Write the inverse statement Now, we can write the inverse of the original statement: \[ \neg P \implies Q \] ### Conclusion Thus, the inverse of the statement "P implies ~Q" is: \[ \neg P \implies Q \]
