A jar contains jelly beans there are 9 red jelly beans, 6 blue jelly beans and 6 green jelly beans. You randomly take two jelly beans out to eat. What is the probability that both are blue? Write your answer as a fraction. You do not need to simplify,

The total number of jelly beans is 21 (9 red + 6 blue + 6 green).

The probability of picking a blue jelly bean on the first try is 6/21.

Since a jelly bean has already been picked, there are only 20 jelly beans left in the jar.

The probability of picking a blue jelly bean on the second try is 5/20 (as only 5 blue jelly beans are left).

Therefore, the probability of picking two blue jelly beans in a row is (6/21) * (5/20) = 30/420 = 3/42.
