The probability that the selected student is 18 to 24 years old is (3pts) 14 | 1039 b. The probability that the selected student is a male that is 25 to 34 years old is (3pts) 1,529 p(Mb5-34) = 1,5838amako.ll 531) = Given that the selected student is female, the conditional probability that she is 25 to 34 years old is (3pts) c.
