According to Masterfoods, the company that manufactures M&M’s, 12% of peanut M&M’s are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. You randomly select four peanut M&M’s from an extra-large bag of the candies. (Round all probabilities below to four decimal places; i.e. your answer should look like 0.1234, not 0.1234444 or 12.34%.) a. Compute the probability that at least three of the four M&M’s are green. b. If you repeatedly select random samples of four peanut M&M’s, on average how many do you expect to be green? (Round your answer to two decimal places.) c. With what standard deviation? (Round your answer to two decimal places.)
