Ch 11: Probability Concepts & Calculations

About This Chapter

Let us demonstrate methods for calculating the probability of various types of events. These video lessons and self-assessment quizzes can check your knowledge and ensure you're ready to answer questions on an upcoming test.

Probability Concepts & Calculations - Chapter Summary

This chapter's lessons will help you better understand the basics of probability. Short video lessons guide you through the different types of events and explain how to calculate the probability of their occurrence. You'll also learn to determine range, mean, median and mode. The lessons cover the following topics:

  • Simple conditional probabilities
  • Probability of independent events
  • Probability of simple, compound and complementary events
  • Probability of dependent and independent events
  • Either/or probability
  • How to calculate mean, median, mode and range

The instructors explore each topic in an engaging manner, explaining the meaning of the numbers used to express probabilities and demonstrating strategies for predicting possible outcomes. Self-assessment quizzes that accompany each lesson will help test your knowledge and familiarize yourself with the test format. With a sound understanding of how probability works, you should be ready for your exam.

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 Events: The 'At Least One' Rule

2. 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.

Probability of Simple, Compound and Complementary Events

3. 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.

Probability of Independent and Dependent Events

4. 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.

Either/Or Probability: Overlapping and Non-Overlapping Events

5. 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.

How to Calculate Mean, Median, Mode & Range

6. How to Calculate Mean, Median, Mode & Range

Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.
