The Approximate Calculation of Two Classical Probabities on product Examination

彭求实．两类有关产品检测古典概率的近似计算．数理统计与管理，１９９７，１６（４），３３～３６．本文改进了一个关于阶乘的不等式，并在此基础上。

This paper improves a factorial inequality. Based on that, we discuss the approximate of two classical probabilities on product examination——binomial and hypergeome hypergeometric distribution.
