Modeling Conditional Probabilities 2

A little background

  • In case you are trying the MARS MAP Classroom Challenges for the first time, it is recommended that you read the Brief Guide for teachers and administrators before you get started.
  • Before the lesson, students work individually on an assessment task that is designed to reveal their current understandings and difficulties. You then review their work and create questions for students to answer in order to improve their solutions.
  • During the lesson, students first work collaboratively on a related task. They have an opportunity to extend and generalize this work. The lesson ends with a whole-class discussion.
  • In a subsequent lesson, students revise their individual solutions to the assessment task.
  • Additional resources for this lesson include: lucky_dip_2_slides.ppt

Objectives

  • To help you assess how well students understand conditional probability.
  • To help you identify and assist students who have the following difficulties representing events as a subset of a sample space using tables and tree diagrams.
  • To help you identify and assist students who have the following difficulties understanding when conditional probabilities are equal for particular and general situations.
