Discrete Math II - 6.4.3 Other Identities Involving Binomial Coefficients

Показать описание
We finish up section 6.4 by looking at a few lesser-known identities. Your textbook contains combinatorial proofs for each identity that we discuss. I didn't want to regurgitate those, so I went through the intuition behind each identity.

part 5 of commenting on all the videos im watching in this series. thank you so much again for these videos they are literally lifesavers and I really really hope you get all the money and recognition you can from these because you genuinely deserve it.
