**Shadow**, Sunday, February 20, 2011 at 9:42pmI don't think MathMate mean to divide the number.

- I'm guessing he say to add the total amount up, and put it as the denominator while the amount of white ball is the numerator. Then you will have your probability of picking a white ball ( Simplify if needed).

**Helper**, Sunday, February 20, 2011 at 10:41pmVanny, you are correct

6/20 = 0.3

or you can leave as 6/20 = 3/10
