| Abstract: | The idea of the proof of combinatorial identities by probability method is to use complete event group,the total probability formula,numerical characteristics of random variable to prove identities,as well as the application of the proof of arranged and combinatorial identities by classical subscheme.Then to illustrate the advantages for the proof of combinatorial identities by the probability method. |
