(a) Find the probability that all five have type B+ blood.

(b) Find the probability that none of the five have type B+ blood.

(c) Find the probability that at least one of the five has type B+ blood.

[since the probability that a person in the U.S. has type B+ blood is 9% or 0.09]

Hence the probability is
