Question

What are the uses of pascal's triangle in real life?

Answer 1

See below for one idea:

Explanation:

One use of Pascal's Triangle is in its use with combinatoric questions, and in particular combinations.

For instance, when we have a group of a certain size, let's say 10, and we're looking to pick some number, say 4, we can use Pascal's Triangle to find the number of ways we can pick unique groups of 4 (in this case it's 210).

To bring in a real life example - let's say our favourite pizza shop offers 10 toppings and for a certain price they'll put on 4. How many unique pizzas can we create? 210.
