一个不定方程解的组数的计数公式及其概率应用

A Counting Number Formula of the Groups of the Solution for a Nondefinite Equation and It′s Applications

本文给出一个不定方程非负整数解的组数的组合计数公式，说明了它在求解一类与数字有关的古典概率方面的应用。

In this paper,a combinatorial counting number formula of the groups of the non-negative integer solution for a nondefinite equation is given. It′s applications in solving a class of classical probability problems related to numbers are illustrated.
