Probability Question: What is the probability that you will take exactly 3 black marbles?

I'm having trouble with my math homework: You are getting 5 chips from a bag of 7 red and black 4. What is the probability that 3 will be black?

11C5 = 462 ways to choose 5 out of total 11 4C3 = 4 ways to choose 3 black 4-7C2 = 21 ways of choosing 2 red 7 so there is 4C3 * 7C2 ways to get 3 black and red 2 p = 4C3 * 7C2 / 11C5 = 84 / 462 = 2 / 11 = 0.181818 ..... ..
