The correct Answer is:
To find the negative of the expression \( p \vee q \) (where \( \vee \) denotes the logical disjunction), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Expression**: The expression \( p \vee q \) represents the logical disjunction of \( p \) and \( q \). This means that the expression is true if at least one of \( p \) or \( q \) is true. 2. **Apply Negation**: The negative of the expression \( p \vee q \) can be represented using the negation symbol \( \neg \). Thus, we write: \[ \neg (p \vee q) \] 3. **Use De Morgan's Law**: According to De Morgan's Laws, the negation of a disjunction can be expressed as the conjunction of the negations. Therefore, we can rewrite the expression as: \[ \neg (p \vee q) = \neg p \wedge \neg q \] Here, \( \wedge \) denotes logical conjunction. 4. **Final Answer**: Thus, the negative of \( p \vee q \) is: \[ \neg p \wedge \neg q \] ### Summary: The negative of \( p \vee q \) is \( \neg p \wedge \neg q \). ---
