Unit 8, Lesson 9
Using Tables for Conditional Probability
Geometry
Preparation
Lesson Narrative
In this lesson, students create and use two-way tables to estimate conditional probabilities and to decide if events are independent. Two-way tables are useful for keeping track of combinations of events and can be used to estimate probabilities from data.
Technology isn't required for this lesson, but there are opportunities for students to choose to use appropriate technology to solve problems (MP5). We recommend making technology available.
- Interpret (in written language) two-way tables to estimate probabilities including conditional probability.
- Use probabilities, including conditional probability, to justify (orally and in writing) that events are dependent or independent.
