From experience, an airline knows that only 80%of the passengers booked for a certain flight actually show up. If 7passengers are randomly selected, find the probabilitythat at least 5of them show up. Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.

(If necessary, consult alist of formulas. Note that the ALEKS calculator allows you to compute binomial probabilities.)
