A certain flight arrives on time 84 percent of the time. Suppose 155 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 125 flights are on time. (b) at least 125 flights are on time. (c) fewer than 139 flights are on time. (d) between 139 and 143, inclusive are on time. (a) P(125) = (Round to four decimal places as needed.) (b) P(X2 125) = (Round to four decimal places as needed.) (c) P(X < 139) = (Round to four decimal places as needed.) (d) P(139
