# Ch 42: Probability Distributions and Statistical Inference

Use the following video lessons and quizzes to help you understand the differences between discrete and continuous random variables. Learn to generate probability distributions, find expected values and apply them to games of chance.

## Probability Distributions and Statistical Inference - Chapter Summary

If you've ever flipped a coin, you already know something of the possible outcomes statisticians take into consideration when they develop probability distributions. Instructors teaching this chapter explain why a countable number of values - like heads or tails - is a type of discrete random variable that can be used to calculate the likelihood of an event's outcome.

They'll also introduce you to the uses of continuous random variables that represent values of infinite number before demonstrating the steps required to generate both discrete and continuous probability distributions, either empirically or theoretically. There are also lessons showing you how to graph probability distributions and find the expected values for each type.

The rest of the chapter helps drive these concepts home. Instructors show you how to apply probability distributions in order to find expected values in games of chance. You can also use this knowledge to compare game strategies and solve other real-life problems. The final lesson explores the uses of probabilities to determine a geometric region's area. By the time you finish this chapter, you should be familiar with the following:

• Discrete random variables
• Continuous random variables
• Probability distributions
• Expected values

Let our informed and experienced instructors help you wrap your head around these topics and more with video lessons that make the material entertaining and approachable. The same content can be found in the transcripts, which also include links to supplementary vocabulary lessons. Self-assessment quizzes are included as well to help affirm your understanding of each lesson's main ideas.
