However, the understand clearly my 'proof' that every prime is odd.

They laugh at the statement that "100% of something is not all of the same something".

Come up with a proof that satisfy my collegues. Do you have enough intelligence for that? Remember tha ...[text shortened]... level the average people. Do you have this kind of brains? Or are you quite alone up there?

All that odd means in essence is 'not divisible by 2'. Therefore every number apart from 2, that is divisible by two will not be a prime number. This means that every prime number will be odd.
Likewise, if we introduced a phrase that meant 'A number not divisible by 3', let's call them obb numbers, then every number apart from 3, that is divisible by 3, will not be a prime number. ie every prime number will be obb.
Can you prove that every prime number is obb?
