The correct Answer is:
To solve the problem, we need to express the negation of the statement \( \sim (p \lor q) \) in words, where \( p \) and \( q \) are defined as follows: 1. \( p: 7 \) is not greater than 4. 2. \( q: \) Paris is in France. ### Step-by-Step Solution: 1. **Identify the Statements:** - \( p \): 7 is not greater than 4. - \( q \): Paris is in France. 2. **Determine the Negation of Each Statement:** - The negation of \( p \) (denoted as \( \sim p \)) is: 7 is greater than 4. - The negation of \( q \) (denoted as \( \sim q \)) is: Paris is not in France. 3. **Combine the Statements:** - The expression \( p \lor q \) means "7 is not greater than 4 or Paris is in France." - The negation \( \sim (p \lor q) \) means "It is not the case that 7 is not greater than 4 or Paris is in France." 4. **Apply De Morgan's Law:** - According to De Morgan's laws, the negation of a disjunction is the conjunction of the negations: \[ \sim (p \lor q) = \sim p \land \sim q \] - Therefore, we can rewrite this as: - \( \sim (p \lor q) \) is equivalent to \( \sim p \land \sim q \), which translates to: - "7 is greater than 4 and Paris is not in France." 5. **Final Statement in Words:** - Thus, \( \sim (p \lor q) \) in words is: "7 is greater than 4 and Paris is not in France."
