根据问题的要求,一一列举问题的解答,或者为了解决问题的方便,把问题分为不重复不遗漏的有限种情况,一一列举这各种情况加以解决,最终达到解决整个问题的目的,这种分析、解决问题的办法叫枚举法.枚举法是概率与统计的基本方法,在新课程改革之前,在教材中,很少涉及枚举法,所有习题基本都可以通过排列和组合进行处理.但是随着时间的推移,逐渐发现使用排列和组合
According to the requirements of the questions, they are listed as examples to explain the problems or, for the convenience of solving the problems, to divide the problems into the limited ones that are not repeated without any omission, to solve the problems one by one and finally reach the goal of resolving the entire problem. This analysis, the solution to the problem is called enumeration method.Enumeration method is the basic method of probability and statistics, before the new curriculum reform, teaching materials, rarely involved in the enumeration method, all exercises can be arranged and combined basic But over time, gradually found the use of permutations and combinations
