Homework Help: Stats (probability)

Posted by Morgan on Wednesday, March 16, 2011 at 12:17am.

Of 10 girls in a class, 3 have blue eyes. If two girls are chosen at random, what is the probability that (i) both have blue eyes, (ii) neither has blue eyes, (iii) at least one has blue eyes?

I have the answers but do not know how to get them. I'm trying to use a tree diagram but I am confusing myself.
