To show that \( p \vee \neg p \) is a tautology and \( p \wedge \neg p \) is a contradiction, we will construct truth tables for both expressions. ### Step 1: Construct the Truth Table for \( p \vee \neg p \) 1. **List all possible truth values for \( p \)**: - \( p \) can either be True (T) or False (F). Thus, we have: - Row 1: \( p = T \) - Row 2: \( p = F \) ...
