摘　　要：为了克服试题库选题组卷过程中不同试卷重复度过高的问题,利用古典概率模型给出一种选题组卷算法,并且计算出满足试卷重复度为80%的试题库的合理的题量为100道题.In order to overcome the high repeatability of different tests generated from the same question pool, this paper provides an algorithm, which based on a classical probability model, for assembling tests, and concludes that 100 questions in the pool are necessary for 80 % of the repeatability.

关 键 词：古典概型 试题库 重复度
