Use the following information to answer the next two questions. Assume M&M candies are randomly selected and grouped in bags of 55 pieces per bag and that 20% of all M&Ms are Blue. 1. What are the mean and standard deviation (to nearest 0.1) of the number of Blue pieces per bag? {You may consider this to be a binomial probability distribution.] 2. What is the probability (to nearest 0.0001) of finding exactly ten Blue M&Ms in any one bag?
