Mars, Inc. states that 24% of its M&M plain candies are blue and that 16% are green. Assume that they are correct and a large random sample of plain M&Ms is randomly selected from the factory. a.) What is the probability that three candies selected from the sample will be either both green or both blue? b.) What is the probability that if four candies were selected from the sample that at least one would be not green and not blue? c.) What is the probability that if twenty M&Ms were eaten randomly from the sample, that exactly six of them would be green? d.) Find the mean and standard deviation for the above binomial probability distribution in part c. Based on that, would it be unusual that exactly six would be green from a random selection of twenty M&Ms? Why or why not?
