Multiply an odd number by an odd gives an even number. Is it certain, likely, even, unlikely or impossible.

It Is Very Impossible

Imposible. When you multiply two odd numbers it will always be odd. This is the same with even. If you multiply two even numbers the answer will always be even. This fact will never change. Now when you are adding two odd numbers, this is where it becomes different. take

7 + 5

Both are odd, but the answer is 12.
