According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose yousit on a bench in a mall and observe people's habits as they sneeze.(a) What is the probability that among 18 randomly observed individuals exactly 6 do not cover their mouth when sneezing?(b) What is the probability that among 18 randomly observed individuals fewer than 3 do not cover their mouth when sneezing?(c) Would you be surprised if, after observing 18 individuals, fewer than half covered their mouth when sneezing? Why? Fourteen jurors are randomly selected from a population of 4 million residents. Of these 4 million residents, it is known that 49% are of a minority race. Of the 14 jurorsselected, 2 are minorities.(a) What proportion of the jury described is from a minority race?(b) If 14 jurors are randomly selected from a population where 49% are minorities, what is the probability that 2 or fewer jurors will be minorities?(c) What might the lawyer of a defendant from this minority race argue?
