A certain flight arrives on time 8484 percent of the time. Suppose 143143 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 108108 flights are on time. (b) at least 108108 flights are on time. (c) fewer than 124124 flights are on time. (d) between 124124 and 128128, inclusive are on time. (a) P(108108)equals=0.00200.0020 (Round to four decimal places as needed.) (b) P(Xgreater than or equals≥108108)equals=0.99800.9980 (Round to four decimal places as needed.) (c) P(Xless than<124124)equals=0.77960.7796 (Round to four decimal places as needed.) (d) P(124124less than or equals≤Xless than or equals≤128128)equals=0.19230.1923 (Round to four decimal places as needed.)
