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.
