According to the Bureau of Transportation Statistics, 81.9% of American Airlines flights were on time in 2017. Assume
this percentage still holds true for American Airlines. For the next 45 flights from American Airlines, use the normal
approximation to the binomial distribution to complete parts a through d.
a. Determine the probability that fewer than 35 flights will arrive on time.
The probability is
(Round to four decimal places as needed.)
