一、概率概率是新课程的重要内容,近年在各地中考中占一定的比重,利用列举法求概率是解决概率问题的重要方法.为帮助同学们掌握列举法求概率的技巧,这里举例进行简单分析,供同学们参考.1.列举法求概率的条件用列举法求概率问题需要一定的条件.因此,满足什么条件的事件,可以用列举法求它的概率,这是
First, the probability of probability is an important part of the new curriculum, in recent years in various places in the test accounted for a certain proportion, the use of enumeration method is to find the probability of probability is an important way to help students grasp the probability of the enumeration method skills, an example here for simple Analysis, for the students to refer to .1 enumerate the conditions for the probability of the formula to use the enumeration method to find the probability of the problem requires certain conditions, therefore, to meet the conditions of the event, you can enumerate the probability of it, which is
