What Is a Factorial?

1. What Is a Factorial?

Maybe it's because I'm a math teacher, but when I watched the Olympics I found myself thinking about how many different ways the swimmers could have finished the race. In this video, you'll learn the answer to this question, why it's important and how it lead to the invention of the mathematical operation called the factorial.

Factorial Practice Problems

2. Factorial Practice Problems

While the definition of factorial isn't complicated, it's easy to make them trickier by throwing a lot of them together and adding in some fractions. Test your skills here with some algebraic examples that make you use factorials without many numbers.

What is the Binomial Theorem?

3. What is the Binomial Theorem?

While the F.O.I.L. method can be used to multiply any number of binomials together, doing more than three can quickly become a huge headache. Luckily, we've got the Binomial Theorem and Pascal's Triangle for that! Learn all about it in this lesson.

Binomial Theorem Practice Problems

4. Binomial Theorem Practice Problems

The binomial theorem can be a really helpful shortcut, but it can also be really confusing. Brush up on your skills with this useful rule in these practice problems!

Blaise Pascal: Contributions, Inventions & Facts

5. Blaise Pascal: Contributions, Inventions & Facts

Blaise Pascal contributed much to mathematics in his short 39 years. In this lesson, you will learn that he laid the foundation for probability. To help his father, Blaise even designed a calculator to make tax calculations easier.

Basic Probability Theory: Rules & Formulas

6. Basic Probability Theory: Rules & Formulas

This lesson contains probability basics and rules, as well as the fundamental law of total probability and Bayes' theorem. Explore these important concepts and then see if you can answer the questions in the follow-up quiz.

Bayes' Theorem Practice Problems

7. Bayes' Theorem Practice Problems

Bayes' theorem is a formula used for computing conditional probability, which is the probability of something occurring with the prior knowledge that something else has occurred. In this lesson, you'll learn how to use Bayes' theorem while completing some practice problems.

Probability Density Function: Definition, Formula & Examples

8. Probability Density Function: Definition, Formula & Examples

A probability density function is a tool for building mathematical models of real-world random processes. In this lesson, we'll start by discussing why probability density functions are needed in probability theory, then we'll provide its definition and several examples of common probability density functions.
