### About This Chapter

## CEOE Middle Level/Intermediate Math: Discrete Probability Distributions - Chapter Summary

The information in this chapter is a refresher to increase your competency before you take the CEOE Middle Level/Intermediate Math test. The lessons here will prepare you for answering test questions in several areas, including:

- The definition of uniform distribution in statistics
- Understanding various types of random variables
- The discrete random variable and finding and interpreting its expected value
- Theoretical and empirical discrete probability distributions and how to find expected values
- The meaning and characteristics of binomial experiments
- The process of using formulas to find binomial probabilities
- Using tables to find binomial probabilities

These text and video lessons use content and hosting by our subject matter experts. At the end of each is a quiz to check your understanding of what was presented. You can print a worksheet of quiz questions and answers and use them for offline study, perhaps even creating flash card study aids. Another feature lets you ask questions of our experts.

### 1. Uniform Distribution in Statistics: Definition & Examples

In this lesson we will explore uniform distributions and learn how to identify two basic types: discrete and uniform. You'll also learn how to recognize both by the shape and characteristics of their graphs.

### 2. Random Variables: Definition, Types & Examples

This lesson defines the term random variables in the context of probability. You'll learn about certain properties of random variables and the different types of random variables.

### 3. Finding & Interpreting the Expected Value of a Discrete Random Variable

Discrete random variables appear in your life a lot more than you think. You can use expected values to find the probability of a discrete random variable, as shown in this lesson.

### 4. Developing Discrete Probability Distributions Theoretically & Finding Expected Values

In this lesson, we will look at generating a theoretical probability distribution for a discrete random variable and introduce the concept of expected value.

### 5. Developing Discrete Probability Distributions Empirically & Finding Expected Values

In this lesson, we will look at creating a discrete probability distribution given a set of discrete data. We will also look at determining the expected value of the distribution.

### 6. Binomial Experiments: Definition, Characteristics & Examples

Binomial experiments happen in your everyday life far more often than you might think. In this lesson, you will learn the characteristics of binomial experiments that will help you identify them.

### 7. Finding Binomial Probabilities Using Formulas: Process & Examples

You can find the probability of getting a certain number of successes when conducting a binomial experiment. In this lesson, you will learn how to find this information using the binomial probabilities formula.

### 8. Finding Binomial Probabilities Using Tables

A binomial probability table can look intimidating to use. However, it can make your life a lot easier when trying to figure out binomial probabilities. This lesson will teach you how to read those tables.

### 9. Mean & Standard Deviation of a Binomial Random Variable: Formula & Example

When working with binomial random variables and experiments, it is important to understand the mean and standard deviation. In this lesson, you will learn how to analyze binomial experiments using the mean and standard deviation of a binomial random variable.

### 10. Solving Problems with Binomial Experiments: Steps & Example

Sometimes when conducting research you will need to use binomial experiments to solve problems. In this lesson, you will learn about binomial experiments and how to use probability to solve problems.
