A box contains 9 red marbles, 6 green marbles, and 10 black marbles. A sample of 11 marbles is to be picked from the box.
How many samples contain exactly 5 green marbles or exactly 3 black marbles?
I keep getting 934992 as the answer but my homework site says that is wrong.

Never mind! I didn't subtract the number of samples with exactly 5 green and 3 black.
