Understanding Binomial Coefficients

This video tutorial explains how to evaluate binomial coefficients using factorials. It covers the definition, provides examples such as 8 above 3, 4 above 0, and 7 above 5, and discusses special cases where n equals r or r is 0. The video also explores scenarios where n is one unit above r, demonstrating the simplification process and the resulting values.

What is the formula for calculating a binomial coefficient?

• n! * r! / (n-r)!

• n! / (r! * (n-r)!)

• (n-r)! / (n! * r!)

• n! / (n-r)! * r!
