A set S is composed of 20 multi-colored objects. 4 objects were chosen randomly from S.
What is the probability that 3 of the chosen objects be blue; knowing that there are 8 blue objects in S ?
So, I don't need hell loads of math theory. I only want steps for a solution and I'll be thankful.
Please help me.
(8/20) x (7/19) x (6/18)
p = (8/20) x (7/19) x (6/18) x (5/17) x 4!
No, that last bit isn't punctuation.
