-----------
Both integers must be odd for the product to be odd.
There are 13 odd integers from 1 to 25
--> (13/25)*(13/25) = 169/625
= 0.2704

You can put this solution on YOUR website! Look at the total number of outcomes,
Looking at the products, the ones that have the first number even make an even product (2,4,6,...,24) so that's 
The ones that have the first number odd, have the second number even on 12 of them so, 
So then,
So then the probability of an odd product is,
