Students are introduced to the Multiplication Rule for both independent and dependent events. Using spinners, they compare probabilities found by looking at the sample space and by using the appropriate formula. They will learn what is meant by a conditional probability and find conditional probabilities, some from a table in a spreadsheet. Last, they will use complements of events to find probabilities of "at least one."
