# Pascal's Triangle

Pascal's triangle is a triangular array of binomial coefficients that can visually illustrate several of their properties.

Pascal's triangle is a college-level concept that would be first encountered in a discrete mathematics course covering combinatorics.

### Prerequisites

Binomial Coefficient: | The binomial coefficient is a notation and function giving the number of ways of picking k unordered outcomes from n possibilities, also known as a combination or combinatorial number. |

Factorial: | The factorial of a positive integer n, denoted n!, is the product of the first n positive integers. |

Probability: | Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions. |
