In a recent study, 29% of people surveyed indicate chocolate was their favorite flavor of ice cream. Suppose we select a sample of ten people and ask them to name their favorite flavor of ice cream. How many of those in the sample would you expect to name chocolate? What is the probability exactly four of those in the sample name chocolate?
