A certain flight arrives on time 80 percent of the time. Suppose 132 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (Round to four decimal places as needed)

(a) exactly 103 flights are on time.

(b) at least 103 flights are on time.

(c) fewer than 99 flights are on time.

(d) between 99 and 100, inclusive are on time.
