# Ch 4: Probability Overview

Watch online video lessons to learn about mathematical sets, subsets, probability and more. Each lesson is accompanied by a short multiple-choice quiz to help check your understanding of these probability topics.

## Probability - Chapter Summary and Learning Objectives

Probability is a measure of how likely something is to occur. In this chapter, you'll learn how to calculate probabilities for different types of events and explore different rules of probability. This chapter can help you understand the following:

• Independent and dependent events
• Calculating simple conditional probabilities
• The relationship between conditional probabilities and independence
• The multiplication and addition rules of probability
• Calculating permutations
