A bag contains 30 red jellybeans and 30 blue jellybeans

A bag contains 30 red jellybeans and 30 blue jellybeans. If 3 jellybeans are removed one at a time, at random and are not replaced, what is the probability that all 3 jellybeans removed from the bag are blue?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
