This Instructional Activity is a part of the Lesson 5, Unit 5, Grade 7. Students read the paragraph silently. In previous lessons, you learned that when the outcomes in a sample space are equally likely, the probability of an event is the number of outcomes in the event divided by the number of outcomes in the sample space. However, when the outcomes in the sample space are not equally likely, we need to take a different approach. This straightforward example lets students experience probabilities given in a table, outcomes with unequal probabilities, adding probabilities, and finding the probability of a complement (i.e., the probability that an event does not happen).
