# Ch 30: Permutation & Combination

### About This Chapter

## Permutation & Combination - Chapter Summary

Our instructors present you with permutations and combinations in this easy-to-follow chapter. Fun video lessons cover how to calculate a permutation and the interesting ways that combinations are used to solve real-world problems. Once you work through this chapter, you will be able to do the following:

- Calculate the probability of a permutation in an example problem
- Identify the formula for circular permutations
- Understand the vital relationship between combinations and probability

Studying is made easy and fun with the video lessons and quizzes offered in this chapter. Use the video tabs feature to skip directly to the portion of the video you'd like to watch for completely flexible learning. Lesson quizzes and a chapter test help you assess your understanding before a big test. Our instructors are available to offer their assistance if you find that you need it.

### 1. How to Calculate a Permutation

A permutation is a method used to calculate the total outcomes of a situation where order is important. In this lesson, John will use permutations to help him organize the cards in his poker hand and order a pizza.

### 2. How to Calculate the Probability of Permutations

In this lesson, you will learn how to calculate the probability of a permutation by analyzing a real-world example in which the order of the events does matter. We'll also review what a factorial is. We will then go over some examples for practice.

### 3. Circular Permutation: Formula & Examples

This lesson introduces the concept of circular permutations along with its formula. Learn how to determine the number of ways to arrange items in a circle, and when you are through take the quiz to see what you have learned.

### 4. Math Combinations: Formula and Example Problems

Combinations are an arrangement of objects where order does not matter. In this lesson, the coach of the Wildcats basketball team uses combinations to help his team prepare for the upcoming season.

### 5. How to Calculate the Probability of Combinations

To calculate the probability of a combination, you will need to consider the number of favorable outcomes over the number of total outcomes. Combinations are used to calculate events where order does not matter. In this lesson, we will explore the connection between these two essential topics.
