A jar contains jelly beans. There are
8
8 red jelly beans,
6
6 blue jelly beans and
6
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 8 + 6 + 6 = 20.
The probability of first picking a blue jelly bean is 6/20, and the probability of picking a second blue jelly bean is 5/19 (since there will be one less jelly bean in the jar).
Therefore, the probability of picking two blue jelly beans is (6/20) * (5/19) = 30/380 = 15/190.
