What is the probability of drawing two balls of the same color from a box containing 20 white balls and 10 black balls?
Well on the first try what is the probability of getting a white ball? If you remove that white ball, what is the probability of getting a white ball on the second try? What would that mean the probability of them both being white is?
Then do the same thing for the black balls...
