The correct Answer is:
To find the negation of the statement "p implies q" (denoted as \( p \implies q \)), we can follow these steps: ### Step 1: Understand the implication The implication \( p \implies q \) can be expressed in terms of logical operations. It is equivalent to \( \neg p \lor q \) (not p or q). ### Step 2: Write the equivalence Thus, we have: \[ p \implies q \equiv \neg p \lor q \] ### Step 3: Negate the equivalence To find the negation of \( p \implies q \), we need to negate the expression \( \neg p \lor q \): \[ \neg(p \implies q) \equiv \neg(\neg p \lor q) \] ### Step 4: Apply De Morgan's Law Using De Morgan's Law, we can convert the negation of a disjunction into a conjunction: \[ \neg(\neg p \lor q) \equiv \neg(\neg p) \land \neg(q) \] ### Step 5: Simplify the expression Now, simplify the expression: \[ \neg(\neg p) \land \neg(q) \equiv p \land \neg q \] ### Conclusion Thus, the negation of \( p \implies q \) is: \[ \neg(p \implies q) \equiv p \land \neg q \] ### Final Answer The negation of \( p \implies q \) is \( p \land \neg q \). ---
