Acertain fight arrives on time 88 percent of the time. Suppose 186 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 159 fights are on time. (b) at least 159 flights are on time. (c) fewer than 161 flights are on time. (d) between 161 and 174, inclusive are on time. (a) P(159) = (Round to four decimal places as needed.) (b) P(X2 159) - (Round to four decimal places as needed.) (c) P(X< 161) - (Round to four decimal places as needed.) (d) P(161 ≤x≤174)=(Round to four decimal places as needed.)
