Web2.2. Proofs in Combinatorics. We have already seen some basic proof techniques when we considered graph theory: direct proofs, proof by contrapositive, proof by contradiction, and proof by induction. In this section, we will consider a few proof techniques particular to combinatorics. WebBinomial coefficients are a family of positive integers that occur as coefficients in the binomial theorem. Binomial coefficients have been known for centuries, but they're best known from Blaise Pascal's work circa 1640. Below is a construction of the first 11 rows of Pascal's triangle. ... WebNote: In particular, Vandermonde's identity holds for all binomial coefficients, not just the non-negative integers that are assumed in the combinatorial proof.
