WEST Math: Probability - Chapter Summary

These quick, accessible video lessons provide a great resource for reviewing the probability concepts you need to know for the WEST Math certification exam. As you work through this chapter, you will review:

How to determine the probability of different types of events
The relationship between independence and conditional probability
Addition and multiplication rules for probability
How to calculate permutation and permutation probability

Video transcripts highlight key terms and provide an additional format for students who prefer an alternative media. Use the lesson quizzes to assess your mastery of the probability material covered here.

Objectives of the WEST Math: Probability Chapter

This chapter is designed to help you master the probability topics you'll likely encounter as you sit for the WEST Math assessment. Lesson quizzes are styled after WEST questions, giving you the chance to introduce yourself to the format and evaluate your exam pace.

You will have four hours and fifteen minutes to answer all 150 multiple-choice questions on the computer-administered exam. Items concerning statistics, probability and discrete mathematics are worth 19% of your test score. The four remaining content domains are as follows: mathematical processes and number sense (19%); patterns, algebra and functions (24%); measurement and geometry (19%); and trigonometry and calculus (19%).

1. Events as Subsets of a Sample Space: Definition & Example

Probability can get very confusing at times. You will find that some words, such as events and subsets, are often referring to the same concept depending on the experiment. Use this lesson to understand the concept of events as subsets.

2. Probability of Simple, Compound and Complementary Events

Simple, compound, and complementary events are different types of probabilities. Each of these probabilities are calculated in a slightly different fashion. In this lesson, we will look at some real world examples of these different forms of probability.

3. Probability of Independent and Dependent Events

Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.

4. How to Calculate Simple Conditional Probabilities

Conditional probability, just like it sounds, is a probability that happens on the condition of a previous event occurring. To calculate conditional probabilities, we must first consider the effects of the previous event on the current event.

5. The Relationship Between Conditional Probabilities & Independence

Conditional and independent probabilities are a basic part of learning statistics. It's important that you can understand the similarities and differences between the two as discussed in this lesson.

6. The Addition Rule of Probability: Definition & Examples

In this lesson, you will learn the differences between mutually exclusive and non-mutually exclusive events and how to find the probabilities of each using the Addition Rule of Probability.

7. The Multiplication Rule of Probability: Definition & Examples

The Multiplication Rule of Probability is a concept you will use frequently when solving probability equations. In this lesson, learn the two different scenarios in which you will use the multiplication rule of probability.

8. How to Use the Fundamental Counting Principle

There are many situations in which you will have to make several decisions simultaneously. The fundamental counting principle will help you determine how many different possible outcomes there are when you have to make multiple simultaneous decisions.

9. 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.

10. 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.

11. 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.
