# Ch 19: Algebra II: Combinatorics

This chapter on combinatorics can show you how to use combinations and permutations to find the probability of certain events. Concise video lessons and practice math problems can help you assimilate the material.

## Algebra II: Combinatorics - Chapter Summary and Learning Objectives

This chapter includes lessons focused on combinatorics, which is the study of countable (also known as finite) mathematical elements. You'll learn about the fundamental counting principle and the purpose of combinations when counting. Lessons also teach you about several probability rules, including the difference between independent and dependent events. Once you complete the chapter, you should have knowledge of the following topics:

• Fundamental counting principle
• Permutations and combinations
• Independent and dependent events
• Conditional probability

Video Objective
Fundamental Counting Principle: Definition and Uses Define and explain the use of the fundamental counting principle when dealing with combinatorics.
How to Calculate a Permutation Differentiate between permutations and combinations, discussing the purpose that combinations and permutations serve when counting.
Math Combinations: Formula and Example Problems Understand the factorial operation when counting down to factorials and show how to use math combinations in order to tell how many differing ways you may select an object from a larger group of items.
Probability of Independent and Dependent Events Differentiate between independent and dependent events, calculating each of these probabilities.
Conditional Probability: Definition and Uses Define conditional probability and its uses in the mathematical and practical world.
