No.

No. A prime number is always odd.

Kind of. The only Prime number that is even is 2.

Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.

Not quite.When two prime numbers of 3 and higher are added together, the result is always even, because all such prime numbers are odd numbers, and when two odd numbers are added together, the result is always an even number.However 2 is a prime number, and 2 is also an even number. Adding 2 (an even number) to a different prime number (an odd number) will always yield an odd number.Only if you don't include "2".

Yes, except for the number 2.

no because 5x3 is 15 and 15 is not a prime number

No, they do not. If one of the prime numbers is 2, you will have an odd number.

3 is the smallest odd prime number.

The lowest odd prime number is 3 .

All prime numbers have only 2 factors which are themselves and one. Al prime numbers are odd numbers except for 2 which is the only even prime number.

Some are. However prime numbers are always odd, with the exception of the number 2.
