A jar contains jelly beans. There are 6 red jelly beans, 6 blue jelly beans and 5 green jelly beans. You

The total number of jelly beans in the jar is 6 (red) + 6 (blue) + 5 (green) = 17.

The probability of picking a red jelly bean first is 6/17.
After picking the red jelly bean, there are now 16 total jelly beans left and 5 green jelly beans left.
So the probability of picking a green jelly bean second is 5/16.

Therefore, the overall probability of picking a red jelly bean first and a green jelly bean second is:
(6/17) * (5/16) = 30/272 = 15/136.

So the probability is 15/136.
