The mailing list of an agency that markets scuba-diving trips to the Florida Keys contains 65% males and 35% females. The agency calls 26 people chosen at random from the list.
(a). What is the probability that 18 of the 26 people are men? (Use the binomial probability formula. Round to four decimal places)
(b). What is the probability that the first woman is reached on the 6th call? (That is, the first 6 calls give MMMMMF. Round to four decimal places).
