## What is Pascal's triangle?

Perhaps Blaise Pascal’s most important contribution to math was his number pattern known as Pascal’s triangle. This number pattern is viewed in the form of a triangle. It is to this day one of the most clever and interesting number patterns. It contains the Fibonacci sequence and is symmetrical. Pascal’s triangle can and is used in many ways. It can be used for different experiments and also is used in classrooms to help teach children about number patterns. Pascal’s triangle is used in ma y probability experiments because it shows probability in an interesting and very clear form. It is commonly used when showing the probability of heads and tails when a coin is flipped. Pascal’s triangle was a major contribution to probability and the understanding of odds.

## Common Sequence in Pascal's Triangle

In Pascal's triangle there are many number patterns, one every common number pattern though is the sequence to the left. In this pattern every number that is side by side can be added together to get a sum. That sum is the number directly below both numbers.

"While gamblers of all eras have picked up much about basic probabilities from experience and intuition, the power of Pascal's new theory took the understanding of odds a major step forward"
