Fran has 16 cds in a box :6 country, 6 rock, 2 dance, and 2 classical. if she takes out one cd without looking, what is the probability that she will pick a rock or country cd?
6/16 is the probability of a rock cd, and 6/16 is the probability of a country cd. add them together to get 12/16 and voila! idk if your teacher wants you to simplify that to 3/4 but usually in probability you don't :)
