Question 286462: 10 white balls, 20 blue balls, 20 red balls are placed in a urn. If two balls are drawn, with replacement, what is teh probability of drawing 2 white balls? and how did we figure this out?

P(2 white balls) = P(white ball AND white ball) = P(white ball)*P(white ball) = (10/50)(10/50) = 100/2500 = 1/25 = 0.04

So the probability is 1/25 which is a 4% chance.
