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.

Dood. You have to bang your head against the math yourself, if you truly want to understand the answer. You've seen more than one answer here, and I'm not going to tell you which one is correct.  Hmph
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
