Suppоse 77% оf flights аrrive оn time. We rаndomly select 12 flights аnd record how many arrive on time. Explain why this is a binomial experiment (Check the four conditions). Find the probability that exactly three of the flights are on time. Round this answer to 6 decimal places. Probability=. Find the probability that six or fewer of the flights are on time. Probability=. Determine the mean and standard deviation of this binomial distribution. Mean= Standard Deviation=
