9th Grade Permutations & Combinations - Course Description

Monday, August 13, 2012

Students work with the concept of expected value and develop a mathematical analysis based on an area model for probability. Probabilistic thinking is often counterintuitive; for this reason, the activities in this unit model concrete experiences. The gambler's fallacy that the next roll of the dice depends on previous rolls is held with conviction even by well-informed adults. One goal of this unit is for students to recognize this fallacy, both in dice games and in real-life situations. More broadly, students come to understand theoretical probability and see how and when it can be used to model and give insight into every day situations.
