A certain flight arrives on time 80 percent of the time. Suppose 197 fights are randomly selected. Use the normal approximation to the binomial to approximate the probabity that (a) exactly 184 fights are on time. (b) at least 184 fights are on time. (c) fewer than 154 flights are on time. (d) between 154 and 184, inclusive are on time. (a) P(184) (Round to four decimal places as needed.)
