    Blue is 6 out of the 20 marbles Orange is 4 out of the 20 marbles Green is 3 out of the 20 marbles Probability is 6/20 * 4/20 * 3/20 I would reduce the 6/20 to 3/10 and the 4/20 to 1/5 so Probability = 3/10 * 1/5 * 3/20 = 9/1000 So you would get a blue then an orange then a green approximately 9 out of every 1000 tries.

    You only do it this way when you "replace" after each draw.
