# Ch 41: Finding Probability

Let out experienced instructors teach you about finding probabilities. With these video lessons and quizzes, you'll learn about and gain practice in using various methods to calculate probabilities.

## Finding Probability - Chapter Summary

By watching the video lessons in this chapter, you'll learn to see events as subsets of a sample space. The use of the concepts and principles of probability is covered, and you'll learn how to describe the outcomes of simple and compound events and use tables to determine if events are independent.

Several lessons cover calculating probabilities using the axioms of probability as well as related theorems and concepts, such as the addition rule, the multiplication rule, conditional probability and independence. You'll learn to use combinations and permutations to solve many types of probability problems. By the end of this chapter, you'll have an understanding of topics that include:

• Probability of simple, compound, complementary, independent and dependent events
• The 'at least one' rule and how it relates to the probability of independent events
• How to calculate simple conditional probabilities
• How to apply the concepts of conditional probability and independence to real life situations
• Probability and the addition and multiplication rules
• Math combinations
• How to calculate permutations and the probability of permutations

Expert instructors will lead you through these video lessons, sometimes using real life examples to explain the topics. Practice lessons will give you a chance to gauge what you've learned, and you can also test your knowledge with the multiple-choice questions at the end of each video lesson. These questions include links back to the video, making it simple to review key points and passages. The lessons also contain written transcripts, with links to the videos.
