| Abstract: | In this paper,through building probability model,by means of complete incident group,complete probability formula and the number characteristics of random variables,several categories of combinatorial identities are proved. This is not only the broader applications of Probability theory,but also fully shows the unique feature of the proving means that using Probability. |
