The correct Answer is:
To solve the problem, we need to analyze both statements provided and determine their truth values based on logical reasoning. ### Step-by-Step Solution: 1. **Identify the Statements**: - Let \( p \): "Delhi is in India". - Let \( q \): "Mumbai is not in Italy". 2. **Construct the Compound Statement**: - The compound statement is \( p \lor q \) (read as "p or q"), which means "Delhi is in India or Mumbai is not in Italy". 3. **Negate the Compound Statement**: - The negation of \( p \lor q \) is denoted as \( \sim (p \lor q) \). - According to De Morgan's Laws, the negation of a disjunction is the conjunction of the negations: \[ \sim (p \lor q) = \sim p \land \sim q \] 4. **Negate Each Statement**: - Negating \( p \): \( \sim p \): "Delhi is not in India". - Negating \( q \): \( \sim q \): "Mumbai is in Italy". 5. **Combine the Negated Statements**: - Thus, \( \sim (p \lor q) = \sim p \land \sim q \) translates to: - "Delhi is not in India and Mumbai is in Italy". 6. **Conclusion for Statement 1**: - The negation of the statement \( p \lor q \) is indeed "Delhi is not in India and Mumbai is in Italy", which confirms that Statement 1 is **True**. 7. **Evaluate Statement 2**: - Statement 2 claims: \( \sim (p \lor q) = \sim p \lor \sim q \). - From De Morgan's Laws, we know that: \[ \sim (p \lor q) = \sim p \land \sim q \] - Therefore, Statement 2 is incorrect because it states that the negation of a disjunction is a disjunction of the negations, which is not true. 8. **Final Conclusion**: - Statement 1 is **True** and Statement 2 is **False**. ### Final Answer: - Statement 1 is true. - Statement 2 is false.
