Chapter 6: Probability Models

In this chapter, you'll learn:

  • To list all possible outcomes for a chance process in a systematic way
  • To use the Addition Rule to compute the probability that event A or event B (or both) occurs
  • To use the Multiplication Rule to compute the probability that event A and event B both occur
  • To compute conditional probabilities: What is the probability that event B occurs given that event A occurs?

As students work through the chapter, they will see a number of problems involving coins, cards, and dice. These familiar devices effectively demonstrate fundamental principles that apply to many probabilistic situations. As students gain understanding, they’ll be able to apply what they've learned to new statistical problems.
