# Ch 54: NES Math: Discrete Probability Distributions

Watch the lessons in our study guide to refresh your knowledge of topics such as random variables and binomial probabilities in preparation for the NES Math exam. These snappy videos and helpful quizzes can provide structure for your study plan.

## NES Math: Discrete Probability Distributions - Chapter Summary

Let us help you prepare for the NES Math test by offering an opportunity to review probability distributions and problems involving them. Our videos cover test topics that include:

• Types of random variables
• How to find the expected value of a discrete random variable
• How to develop discrete probability distributions empirically and theoretically, and find expected values
• Characteristics of binomial experiments
• How to find binomial probabilities with formulas and tables
• Standard and mean deviation of a binomial random variable
• How to solve problems with binomial experiments

These lively lessons contain plenty of examples and practice problems to help you refresh your understanding, and each is followed by a short self-assessment quiz. You can study anytime on a computer or mobile device, and there's a sheet of quiz questions to print if you want to study offline. Have questions?

### NES Math: Discrete Probability Distributions Objectives

Five states make the NES Math test one of the requirements for obtaining certification to teach math at the secondary level. Questions on the test are sectioned into five content domains, and those on discrete probability distributions are in the Statistics, Probability, and Discrete Mathematics domain. This part of the test accounts of 19% of the total scoring.

All questions on the NES Math test are multiple-choice, like the questions on the lesson quizzes and chapter exam in our study guide. You'll be asked to answer a question or solve a problem and choose the correct answer from several options. Completing our quizzes and the chapter exam will provide experience answering these types of questions and also offer a good way to assess your learning and see where extra review might be useful.
