数学课上,老师介绍了概率的三种求法:枚举法、列表法、画树状图法.课后,杨洋、小明和小亮对“求事件发生的概率,哪种方法更好”这个问题进行了激烈的争辩.他们三个互不相让吵得不可开交.不得已,一起找到王老师来裁定.王老师:这里我们不能笼统地说哪个更好,要具体问题具体分析.我先来说说枚举法.枚举法确定概率是一种行之有效的方法.枚举法,常常称之为穷举法,是指从 In math class, the teacher introduced three methods of probability: enumeration method, list method, and painting tree method. After class, Yang Yang, Xiao Ming, and Xiao Liang asked the probability of event occurrence, which method is better. "This issue has been fiercely debated. The three of them were in no quarrel with each other. The last resort, to find Mr. Wang together to rule. Teacher Wang: We can’t say which is better here. We must analyze specific issues. I will Let’s talk about enumeration. Enumeration is a proven method of determining probability. The enumeration method, often called the exhaustive method, refers to
