The correct Answer is:
To solve the problem, we need to analyze the logical statement given: \((q \land \neg r) \implies p\). We will break it down step by step. ### Step 1: Understand the Components We have three statements: - \(p\): Aman will come today. - \(q\): Aditi will be at her home. - \(r\): They will go to the party. The expression we need to analyze is \((q \land \neg r) \implies p\). ### Step 2: Rewrite the Implication Recall that an implication \(A \implies B\) can be rewritten using logical equivalence as \(\neg A \lor B\). Thus, we can rewrite our expression: \[ (q \land \neg r) \implies p \equiv \neg(q \land \neg r) \lor p \] ### Step 3: Apply De Morgan's Law Using De Morgan's Law, we can simplify \(\neg(q \land \neg r)\): \[ \neg(q \land \neg r) \equiv \neg q \lor \neg(\neg r) \equiv \neg q \lor r \] ### Step 4: Substitute Back into the Expression Now substitute this back into our rewritten implication: \[ \neg(q \land \neg r) \lor p \equiv (\neg q \lor r) \lor p \] ### Step 5: Rearranging the Expression Using the associative property of logical disjunction, we can rearrange this expression: \[ \neg q \lor r \lor p \] ### Conclusion Thus, the statement \((q \land \neg r) \implies p\) is logically equivalent to: \[ \neg q \lor r \lor p \]
