Probability Concepts - Chapter Summary
Refresh your memory about probability concepts by going through the lessons in this chapter. Each lesson addresses a different aspect of probability concepts, so you can review each aspect individually until you feel confident about moving on to the next lesson. Topics covered in this chapter include:
- An overview and definition of mathematical probability
- The formula and examples of theoretical probability
- Probability of complementary, compound, and simple events
- Non-overlapping and overlapping probability events
- Probability of dependent and independent events
Before you commit to using any certification or test prep study guides, you will want to know who made them and whether you can trust that individual. When you use our materials, you can be confident that we only allow the most experienced educators to design our chapters. Our instructors have years of experience in their fields of expertise, so they possess extensive knowledge of key terms, definitions, major concepts, and much more.
Besides years of experience, our instructors design our chapters with your needs in mind. For example, they know that you are viewing this material in preparation for some sort of upcoming test. Therefore, they design each lesson to help you refresh your memory concerning the most essential details. Our instructors know not to waste your time with meaningless data, and they keep the important information well-organized so that you can find exactly what you need.
1. What is Probability in Math? - Definition & Overview
Remember throwing a quarter and calling out heads or tails? Learn what this has to do with probability. Also learn how you can use your newly-learned skills from this lesson to help you decide whether you should play heads or tails at all!
2. What is Theoretical Probability? - Definition, Formula & Examples
Have you ever heard someone ask, 'What are the odds?' Usually what it is meant is, 'How likely is it that an event will happen?' This lesson explores finding the likelihood, or theoretical probability, that an event could occur.
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.
4. 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.
5. 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.
