# Ch 53: PLACE Mathematics: Probability

### About This Chapter

## PLACE Mathematics: Probability - Chapter Summary

The lessons in this chapter can be used to both review and reinforce your knowledge of calculating the likelihood of possible outcomes based on certain criteria and other probability scenarios. Experienced instructors teach the video lessons that outline topics you'll need to know for the exam, such as:

- Events as subsets of a sample space
- Simple, compound and complementary probability
- Ways to calculate the probability of independent and dependent events
- Simple conditional probability
- Conditional probabilities and independence
- How to use the addition and multiplication rules of probability
- Using the fundamental counting principle
- The math combination formula
- Permutation and the probability of permutations

After watching the engaging video lessons in this chapter, take the corresponding multiple-choice quizzes to assess your understanding. If you have any questions about the probability concepts covered, you can submit a question to our expert instructors.

### Objectives of the PLACE Mathematics: Probability Chapter

Understanding how to apply the concepts of probability is one component of the PLACE math exam. The topics you'll study in this chapter fall under the Statistics and Probability subset of the exam, which comprises 19% of the total math test.

The questions on the exam are all multiple choice and require you to select the best answer. Get the practice you need answering these questions and find out where you may need additional help by using our multiple-choice quizzes at the end of each lesson.

### 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.
