When y = 3, which of the following is FALSE?

A. y is prime and y is odd

B. y is odd or y is even

C. y is not prime and y is odd

D. y is odd and 2y is even

I'am not sure about this

well, 3 is an odd number and it is prime

and 2y or 6 is clearly even.

So which choices do you think are false ?

To determine which statement is FALSE when y = 3, let's analyze each option:

A. y is prime and y is odd:
To check if y is prime, we need to verify if it is divisible only by 1 and itself. In this case, 3 is indeed prime. Also, y = 3 is odd since it is not divisible by 2. Therefore, statement A is TRUE.

B. y is odd or y is even:
When we substitute y = 3, it is clear that 3 is odd. So, statement B is TRUE.

C. y is not prime and y is odd:
As we already confirmed, y = 3 is actually prime. Therefore, statement C is FALSE.

D. y is odd and 2y is even:
Since y = 3 is odd, statement D is TRUE.

So, the FALSE statement is C. y is not prime and y is odd.
