Chapter 7.1: Random Variables and Discrete Probability Distributions

ADMS 2320: TERM TEST #2 PREP · Fall 2024 Chapter 7.1: Random Variables and Discrete Probability Distributions

Discrete outcomes can be counted:

  • How many TVs in your house?

By contrast, continuous outcomes are typically measured

  • How much do you weigh?

Chapter 7 focuses on the probabilities of multiple DISCRETE outcomes.
