Binomial Coefficients

EDIT*****
I made a mistake when explaining Pascals identity. I expressed the identity as a product of binomial coefficients, when in fact it should be a sum of binomial coefficients. The same proof ideas hold, you just need to add the binomial coefficient instead of multiplying them.

In this video, we explore binomial coefficients and prove an identity about them using combinatorial methods.
