摘要
文章讨论了差分方程在古典概率中的计算以及随机变量数字特征求解问题中的巧妙应用,说明了差分方程在处理概率问题上也具有较强的实用价值。
In this paper, the skillful application of difference equation in the calculation of the classical probability and random variables＇ mathematical expectation is studied. It is shown that difference equation has strongly practical value in probability.
