In solving a binomial problem, if the evaluation required only finding the probability of all P events, and N = 40, evaluating P ⁴⁰ would be more accurate than using the normal approximation. Assume no rounding. A) T B) F C) It depends on the value of P D) if P = Q = .50, the normal approximation would be more accurate.

If the problem only involves finding the probability of a specific number of events (in this case, P events), and N is large enough (N = 40 is certainly large enough), then using the binomial formula to calculate the probability is more accurate than using the normal approximation. The normal approximation becomes more accurate as N gets larger, but in this case, it is not necessary.
