Fora binomial random variable X m B[. = 8,1) = 0.8), find the probability P(X = 7): P(X = 7) = [ ] (Round the answer to 4 decimal places} United Airlines' flights from Chicago to Atlanta 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 = The probability that at most 4 flights are on time is = The probability that at least 5 flights are on time is =
