Unit 8, Lesson 9
Multi-step Experiments
Grade 7
Preparation
Lesson Narrative
In this lesson, students continue writing out the sample spaces for chance experiments that have multiple steps and also begin using those sample spaces to calculate the probability of certain events. Students must reason quantitatively and abstractly to make sense of the situations and represent the sample spaces mathematically (MP2).
An optional activity provides additional practice writing probabilities of events based on the sample space. The situation in this activity involves drawing cards without replacement, so the structures are not as symmetric as other examples.
- Choose a method for representing the sample space of a compound event, and justify (orally) the choice.
- Use the sample space to determine the probability of a compound event, and explain (orally, in writing, and using other representations) the reasoning.
Let’s look at probabilities of experiments that have multiple steps.
