question 1

From experience, an airline knows that only 80% of the passengers booked for a certain flight actually show up. If 10 passengers are randomly selected, find the probability that fewer than 9 of them show up. Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.) X 5 ?The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 70% of planted seeds will germinate. Suppose the manufacturer is correct. If 6 seeds planted with the fertilizer are randomly selected, what is the probability that more than 3 of them germinate? Cam.r your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.) [D x b 9
