| 摘 要： | 本文通过几个实例说明对一些组合恒等式的证明可以用求概率的方法得到。甚至运用求随机变量的数字特征(如数学期望)加以证明,这就为我们解决组合恒等式证明问题带来了极大的方便。

| Abstract: | This dissertation mainly discusses the proof to some combinatorial identities which can be obtained by beseeching the probability,even by beseeching the mathematical expectation of random variable through several examples.It's a great conve- nience to solve this kind of problem. |
