Question 1008133: A box contains 15 marbles. Five of the marbles are blue, six are green, and four are red. If 4 marbles are selected from the box one at a time, find the probability of selecting 4 green marbles if selection is without replacement.

Without replacing them, the odds change.
Then we multiply
6/15 * 5/14 * 4/13 * 3/12 = .011 = 1.1%
