Your flight has been delayed: At Denver International Airport, 70% of recent flights have arrived on time. A sample of 10 flights is studied. Round the probabilities to at least four decimal places. Part 1 of 4 (a) Find the probability that all 10 of the flights were on time. The probability that all 10 of the flights were on time is 0.0282. (b)Find the probability that exactly 8 of the flights were on time.The probability that exactly 8 of the flights were on time is 0.2335 (c)Find the probability that 8 or more of the flights were on time. The probability that 8 or more of the flights were on time is 0.3828 (d)Would it be unusual for 9 or more of the flights to be on time? Use a cutoff of 0.05. It (Choose one)be unusual for 9 or more of the flights to be on time since the probability is .
