American Airlines' flights from Boston to Dallas are on time 90 % of the time. Suppose 8 flights are randomly selected, and the number on-time flights is recorded. Round answers to 3 significant figures. The probability that exactly 7 flights are on time is = 0.3826 The probability that at most 6 flights are on time is = 0.1868 The probability that at least 5 flights are on time is = 0.082
