摘要
针对可能取值有无限个的离散型随机变量,以数学分析中的级数为工具推演切比雪夫大数定律,研究了期望、方差及相关的序列,得到了关于离散型随机变量有针对性的推论.
Possible values have infinite number of discrete random variables, so that this paper deduced Chebyshev law of large numbers with series, studied expectation, variance and relevant sequences, and obtained the inference that special random variables had pertinence.
