You can't miss. The probability is 10/10 = 1

There are two answers for this question. For one, there is the smart-alec answer that the probability is 1, because those are the only colors possible, so the ball will be one of those colors.
But if you want a non-smart-alec answer (which I assume you do because you are not like me and you don't want to be lazy), do these steps:
Add the amount of balls. 5+2+3=10
Put the amount of whatever color balls over the amount of total balls.
Green=5/10
Yellow=2/10
Purple=3/10
Reduce them all:
Green=1/2
Yellow=1/5
Purple=3/10
The fractions are the probability.
