            We have a binomial distribution problem/experiment.

            The formulas below are standard formulas for a binomial distribution probability. 


(a)  P = %281-0.09%29%5E4 = 0.91%5E4 = 0.68574961  (rounded).    ANSWER


(b)  P = %281-0.09%29%5E3%2A0.09 = 0.91%5E3%2A0.09 = 0.06782  (rounded).    ANSWER


(c)  P = C%5B4%5D%5E1%2A0.09%2A%281-0.09%29%5E3 = 4%2A0.09%2A0.91%5E3 = 0.2713  (rounded).    ANSWER

Solved.
