Ch 53: AEPA Middle Grades Math: Probability

About This Chapter

Arizona now uses the National Evaluation Series (NES) Middle Grades Mathematics test for middle grades math certification instead of the AEPA exam. Prepare for this NES test using the video lessons in this chapter to review the basics concepts of probability.

AEPA Middle Grades Math: Probability - Chapter Summary

In this chapter, our experienced instructors will cover the basic concepts of probability to help you prepare for the NES Middle Grades Mathematics exam. These lessons will review:

  • Calculating simple conditional probabilities
  • Determining the probability of independent and dependent events
  • Fundamental counting principle
  • Permutations and calculating their probability
  • Math combinations and how to calculate their probabilities

Viewing the short video lessons in this chapter will help you cover the material quickly and help you remember it longer. If you need to review a single topic or two, video tags make it easy. You can also use the transcript to quickly look up terminology. And, each lesson includes a self-assessment quiz - perfect for confirming prior knowledge or newly mastered skills as you study for the NES Middle Grades Mathematics exam. If anything is unclear, our subject experts are available to help.

How to Calculate Simple Conditional Probabilities

1. 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.

Probability of Independent and Dependent Events

2. 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.

How to Use the Fundamental Counting Principle

3. 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.

How to Calculate a Permutation

4. 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.

How to Calculate the Probability of Permutations

5. 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.

Math Combinations: Formula and Example Problems

6. 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.

How to Calculate the Probability of Combinations

7. 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.
