According to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on a bench in a mall and observe people's habits as they sneeze. Complete parts (a) through (c). (a) What is the probability that among 12 randomly observed individuals, exactly 4 do not cover their mouth when sneezing? Using the binomial distribution, the probability is 0.2096 . (Round to four decimal places as needed.) (b) What is the probability that among 12 randomly observed individuals, fewer than 5 do not cover their mouth when sneezing? Using the binomial distribution, the probability is (Round to four decimal places as needed.)
