Ch 5: Discrete Probability Distributions: Help and Review

About This Chapter

The Discrete Probability Distributions chapter of this College-Level Principles of Statistics Help and Review course is the simplest way to master discrete probability distributions. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of discrete probability distributions.

Who's it for?

Anyone who needs help learning or mastering college statistics material will benefit from taking this course. There is no faster or easier way to learn college statistics. Among those who would benefit are:

  • Students who have fallen behind in understanding random variables or working with the expected value of a discrete random variable
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning math (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about discrete probability distributions
  • Students who struggle to understand their teachers
  • Students who attend schools without extra math learning resources

Lotteries: Finding Expected Values of Games of Chance

7. Lotteries: Finding Expected Values of Games of Chance

Most of us won't have a problem with winning the lottery. But is it a realistic goal? Do you really have a chance? In this lesson, learn how luck and probability collide when finding expected values in games of chance.

Comparing Game Strategies Using Expected Values: Process & Examples

8. Comparing Game Strategies Using Expected Values: Process & Examples

While statistics and probability leave a lot to chance, we can use expected values to help inform our decisions. This lesson shows us how to use expected values to make the best determinations possible.

How to Apply Discrete Probability Concepts to Problem Solving

9. How to Apply Discrete Probability Concepts to Problem Solving

Discrete probability concepts, such as expected value, success, and failure, can be used to help you solve real-world problems and inform you when making decisions.
