According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 82.9%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below.
a. Determine the probability that, of the next 30 flights from this airline, less than 22 flights will arrive on time.
P(x<22) = ?

According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 81.2%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below. c. Determine the probability that, of the next 30 flights from this airline, 25, 26, 27, or 28 flights will arrive on time.
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 46 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 36 flights will arrive on time. (Round to four decimal places as needed.) B. Determine the probability that exactly 32 flights will arrive on time....

A government's department of transportation reported that in2009, airline A led all domestic airlines in on-time arrivals for domestic flights, with a rate of 83.2%. Complete parts a through e below. a.What is the probability that in the next six flights, exactly four flights will be on time?The probability is nothing. (Round to four decimal places as needed.)
