This Instructional Activity is a part of the Lesson 7, Unit 5, Grade 7. A previous lesson introduced tree diagrams as an effective method of displaying the possible outcomes of certain multistage chance experiments. Additionally, in such situations, tree diagrams were shown to be helpful for computing probabilities. In those previous examples, diagrams primarily focused on cases with two stages. However, the basic principles of tree diagrams can apply to situations with more than two stages. Discuss examples in which a tree diagram could organize and visualize outcomes. Pose the following discussion problems to students, and have them sketch trees as possible ways to organize outcomes.
