Here are the solutions to the questions:
1. The negation of the compound statement (p∧∼q) is
Step 1: Apply De Morgan's Law.
The negation of (p∧∼q) is ∼(p∧∼q). According to De Morgan's Law, ∼(A∧B)≡∼A∨∼B.
∼(p∧∼q)≡∼p∨∼(∼q)
Step 2: Simplify the double negation.
The negation of a negation is the original statement, so ∼(∼q)≡q.
∼p∨q
The negation of the compound statement
