Answer:
30
Step-by-step explanation:
5 blue balls and 3 white balls
We need 2 blue balls in every way. We therefore multiply 5 by 2 so we get 10.
Lastly we have 3 white balls but only 1 is needed to complete a set. So we should multiply 10 by 3. Therefore, we get 30 different ways.
This is only what I know. I don't have any idea if it's correct or not. :)
