The statement is false.
Consider the number 9. Odd, but not prime.

The mathematics major says "This is false. 1 is an odd integer, and it's not prime, nor composite for that matter. 9 is another example of an odd integer that isn't prime. So there you have more than one counter-example to the claim."
The physics major says "Well let's see. 1 is prime. 3 is prime. 5 is prime. 7 is prime. 9 isn't prime but that's just experimental error. 11, 13...yeah, all odd numbers are prime."
The Computer Science major writes a program that prints on the screen "1 IS PRIME. 1 IS PRIME. 1 IS PRIME. 1 IS PRIME..."

All odd integers are not prime.
9 is an odd number.
9 is divisibe by 3, therefore 9 is not prime.
Therefore, not all odd numbers are prime.

All odd integers are not prime. 21 is odd and is is not prime, 3 * 7 = 21, so 21 is not prime.

This should be interesting since all odd integers are certainly -not- prime. In fact, the product of -any- two odd numbers is odd.

Maybe you meant "prove that all prime numbers are odd".
even that is not true since 2 is both prime and even, but it is the only one.
