AI Generated Solution

The correct Answer is:
To solve the problem of finding the equivalent statement for `~(~p ∧ q)`, we will use logical equivalences step by step. ### Step 1: Identify the expression We start with the expression: \[ \sim(\sim p \land q) \] ### Step 2: Apply De Morgan's Law According to De Morgan's Law, the negation of a conjunction can be expressed as the disjunction of the negations. Therefore, we can rewrite the expression as: \[ \sim(\sim p \land q) = \sim(\sim p) \lor \sim(q) \] ### Step 3: Simplify the negation Now, we simplify the negation of `~p`: \[ \sim(\sim p) = p \] Thus, the expression becomes: \[ p \lor \sim q \] ### Final Answer The statement `~(~p ∧ q)` is equivalent to: \[ p \lor \sim q \]
