A flashlight has 8 batteries, 3 of which are defective. If two different batteries are selected at random, what is the probability that both of them will be good? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This would be (5/8)*(4/7), with one good one and one of the total decreasing in the numerator and denominator respectively.
That product is 20/56 or 5/14 (0.36) probability.
