摘要
组合数恒等式的证明,一般用组合数公式及性质直接证明。本文利用组合方法、概率方法和二项式法,证明了某些组合数恒等式,为证明组合数恒等式开辟了新的思路。
In general, identities regarding combinatorial numbers are proved by using the combinatorial formulae and properties. In this paper, a new method of proving combinatorial identities, which uses combinations, probability and binomials, has been tested.
