A certain flight arrives on time 83 percent of the time. Suppose 125 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that
(a) exactly 92 flights are on time.
(b) at least 92 flights are on time.
(c) fewer than 112 flights are on time.
(d) between 112 and 116 inclusive are on time.
(Round to four decimal places as needed.)
