A manufacturer of game controllers is concerned that their controller may be difficult for left-handed users. They set out to find lefties to test. Suppose that about 84% of the population is right-handed. They select a sample of twelve customers at random in their stores. Complete parts a through e below. The probability that there are no more than 10 righties is 0.999 (Round to three decimal places as needed.) d) What is the probability that there are exactly 6 of each? CHE The probability that there are exactly 6 of each is (Do not round until the final answer. Then round to five decimal places as needed.) e) What is the probability that the majority is right-handed? The probability that the majority is righthanded is (Do not round until the final answer. Then round to three decimal acos as needed.)
