About This Chapter

Let us guide you through your preparations for the NES Essential Academic Skills Subtest III Math test with quality instruction and practice quizzes. Watch comprehensive video lessons to refresh your knowledge of probability as you study for exam.

NES Essential Academic Skills Math: Probability - Chapter Summary

When studying for the NES Essential Academic Skills Subtest III Math test, it's good to familiarize yourself with the topics you haven't explored in months - or even years. The lessons in this chapter help you revisit probability so you can address the following on the exam:

  • Analyzing the probability of independent and dependent events
  • Examining the probability of simple, compound and complementary events
  • Understanding either/or probability and overlapping and non-overlapping events
  • Discussing the probability of independent events and 'at least one' rule
  • Calculating simple condition probabilities and the probability of combinations

Subject-matter experts make studying fun by presenting an in-depth look at probability with the help of entertaining visual effects. This unique approach to instruction can keep you engaged in the lesson concepts and improve your ability to succeed on the exam.

NES Essential Academic Skills Math: Probability Chapter Objectives

As a prospective educator, your state might require you to take the NES Essential Academic Skills Subtest III Math test, which is one of four total subtests. Earning a passing score of 220 on the subtest could help you secure teaching licensure or certification. The multiple-choice exam includes 45 questions that are broken into five test competencies that gauge your understanding of various math concepts. The topics in this probability chapter are found the fourth test competency, which examines probability and statistics.

Prepare for this subtest by watching the video lessons or reviewing full video transcripts with helpful vocabulary words. You can also take quizzes and a chapter exam to reinforce concepts learned in the lessons.

Probability of Independent and Dependent Events

1. 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.

Probability of Simple, Compound and Complementary Events

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.

Either/Or Probability: Overlapping and Non-Overlapping Events

3. Either/Or Probability: Overlapping and Non-Overlapping Events

Statistics is the study and interpretation of a set of data. One area of statistics is the study of probability. This lesson will describe how to determine the either/or probability of overlapping and non-overlapping events.

Probability of Independent Events: The 'At Least One' Rule

4. Probability of Independent Events: The 'At Least One' Rule

Occasionally when calculating independent events, it is only important that the event happens once. This is referred to as the 'At Least One' Rule. To calculate this type of problem, we will use the process of complementary events to find the probability of our event occurring at least once.

How to Calculate Simple Conditional Probabilities

5. 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.

How to Calculate the Probability of Combinations

6. 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.
