What is the probability that you will select a piece of chocolate candy? b) What is the probability that you will select a Starburst? Now assuming sampling without replacement: c.) If you select a random sample of n = 4 and the first three candies are a 2 Kit-Kats and a Skittles, what is the probability that you will select a chocolate piece of candy as the fourth item? d.) If you select a random sample of n = 4 and the first three candies are 1 Kit-Kat, 1 Skittles, and 1 Hershey bar, what is the probability that the final candy will be a Starburst?Explanation / Answer
