The correct Answer is:
To determine the truth value of the statement “Neither 27 is a prime number nor divisible by 4,” we will break it down step by step. ### Step 1: Identify the Statements Let: - \( p \): "27 is a prime number" - \( q \): "27 is divisible by 4" ### Step 2: Determine the Truth Values of \( p \) and \( q \) - **Is 27 a prime number?** A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. The number 27 can be divided by 1, 3, 9, and 27. Since it has divisors other than 1 and itself, **27 is not a prime number**. Thus, the truth value of \( p \) is **False**. - **Is 27 divisible by 4?** To check if 27 is divisible by 4, we divide 27 by 4, which gives us 6.75. Since 27 does not yield a whole number when divided by 4, **27 is not divisible by 4**. Thus, the truth value of \( q \) is **False**. ### Step 3: Negate the Statements The original statement is "Neither 27 is a prime number nor divisible by 4," which can be expressed as: - Negation of \( p \): "27 is not a prime number" (True) - Negation of \( q \): "27 is not divisible by 4" (True) ### Step 4: Combine the Negated Statements The statement can be rephrased using logical conjunction (AND): - "27 is not a prime number AND 27 is not divisible by 4" This can be represented as: - \( \neg p \land \neg q \) ### Step 5: Determine the Truth Value of the Combined Statement Since both \( \neg p \) and \( \neg q \) are **True**, we have: - \( T \land T = T \) ### Final Conclusion The truth value of the statement “Neither 27 is a prime number nor divisible by 4” is **True**. ---
