In a recent survey, 30% indicated chocolate was their favorite flavor of ice cream Suppose we select a sample of nine 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? (Round your answer to 2 decimal places.) What is the probability exactly five of those in the sample name chocolate? (Round your answer to 4 decimal places.) What is the probability five or more name chocolate? (Round your answer to 4 decimal places.)
