Question

a magazine rack contains 5 sports magazines, 7 new magazines, and 10 fashion magazines. after a magazine is chosen, it is not replaced. find the probability of randomly choosing two fashion magazines.

Answer 1

10/(5+7+10) = 10/22 = 5/11 chance of a fashion magazine on 1st choice

9/21 = 3/7 chance of a fashion magazine on 2nd choice

5/11 x 3/7 = 15/77 chance of both being fashion magazines
