6. According to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will cover his or her mouth with a tissue, handkerchief, or elbow (the method recommended by health officials) is 0.047. Suppose you sit on a bench in a mall and observe people's habits as they sneeze. (a) What is the probability that among 15 randomly observed individuals exactly 2 cover their mouth with tissue, handkerchief, or elbow? (b) What is the probability that among 15 randomly observed individuals fewer than 3 cover their mouth with a tissue, handkerchief, or elbow?
