# Ch 5: Discrete Probability Distributions

Watch online math video lessons and learn about random variables, expected values, binomial probabilities and more. These easy-to-follow lessons are just a portion of our online study guide and video collection.

## Discrete Probability Distributions - Chapter Summary and Learning Objectives

Let our knowledgeable instructors introduce you to the formulas associated with discrete probability distributions and show you how they can be used to solve real-world problems. Video lessons and transcripts provide plenty of examples and practice problems to walk you through this subject matter. By the end of this chapter, you should be able to do the following:

• Find expected values using theoretical and empirical probability distributions
• Determine a binomial random variable's mean and standard deviation
• Find binomial experiment probabilities
• Use probability to evaluate game strategies
