**Fred**, Thursday, December 8, 2011 at 9:24amThis answer was scored wrong, but I do not know why. If someone would kindly show me the error, I would appreciate it.

First choice probability: 5/20

Second choice probability: 6/19

Third choice probability: 9/18

Total Probability: (5/20)(5/19(9/18)=3/76

This answer is not featured above but the math seems correct. Each successive choice has fewer balls remaining, and the correct number of the desired balls for the next choice still remains in the bag for all the choices. The total probability is the product of the probability of each choice.

**Andrew**, Tuesday, May 27, 2014 at 4:00pmthe answer Red then blue the red is D.

1 of 38 or 2.63% chance

5 red chances /20 balls *

9 blue /19 * 4 red balls left /18

= .25 X .47368 * .2222 = .0263

or 1/38
