Complete parts (a) through (e) below. a. Using the binomial distribution, what is the probability that in the next six flights, four flights will be on time? The probability is (Round to four decimal places as needed.) b. Using the binomial distribution, what is the probability that in the next six flights, all six flights will be on time? The probability is (Round to four decimal places as needed.) c. Using the binomial distribution, what is the probability that in the next six flights, at least four flights will be on time? The probability isO (Round to four decimal places as needed.)
