A certain flight arrives on time 89 percent of the time. Suppose 135 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that ​(a) exactly 127 flights are on time. ​(b) at least 127 flights are on time. ​(c) fewer than 117 flights are on time. ​(d) between 117 and 129​, inclusive are on time.
