古典概型是指研究问题中,那些基本事件数有限,且各基本事件发生的概率都相等的一类问题。虽概率计算公式简单,P(A)==事件A所含基本事件数n/样本空间中基本事件总数m但在实际计算中,题目五花八门,内容繁多,对初学者来说,常有束手无策之感。现对古典概型问题加以抽象, Classical profile refers to a class of problems in which the number of basic events is limited and the probability of occurrence of each basic event is equal. Although the probability calculation formula is simple, P(A)==the number of basic events contained in event A/the total number of basic events in the sample space but in practical calculations, the subject is varied and has a wide range of contents. For beginners, there is often no way to deal with it. sense. Now abstract the classical model problem.
