            It is a standard binomial distribution problem.

                        Part ( a )

The number of trials is n=25; the number of successful trials is 15; the probability of success for each single individual trial is p = 0.75. The formula to calculate the probability is P = P(n=25; k=15; p=0.75) = = . The resulting number is P = 0.041658351 = 0.04166 (rounded). ANSWER

Part (a) is solved.

Solve part (b) in the same way.
