### 1. 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.

### 2. Pascal's Triangle: Definition and Use with Polynomials

Pascal's Triangle is defined and discussed briefly. Following the introduction to the triangle, its use in expanding polynomial powers is elaborated with examples.

### 3. How to Use the Binomial Theorem to Expand a Binomial

In this video lesson, you will see what the binomial theorem has in common with Pascal's triangle. Learn how you can use Pascal's triangle to help you to easily expand a binomial.

### 4. The Relationship Between Pascal's Triangle & Combinations

Pascal's triangle shows many important mathematical concepts like the counting numbers and the binomial coefficients. In this lesson, we show how Pascal's triangle is related to combinations.

### 5. Finite Sequence: Definition & Examples

After completing this lesson, you will be able to identify a finite sequence and different types of finite sequences. You will also be able to distinguish mathematical patterns of finite sequences.

### 6. What is a Finite Series?

Read this lesson to learn how finite series are necessary for things such as the Binomial Theorem. You'll also learn how some other mathematical concepts can only be performed with finite series.

### 7. Calculating Binomial Probability: Formula & Examples

When we are calculating probabilities and there are only two possible outcomes, we can consider using the binomial probability. In this lesson we will look at the conditions for using this probability, the formula and some examples that clarify how to use it.

### 8. Binomial Distribution: Definition, Formula & Examples

You have a probability distribution to create, which one do you use? That depends. In this lesson, learn about binomial distributions, get examples and criteria for their use, and learn how to calculate the binomial distribution formula.
