论文部分内容阅读
概率是新课程标准下的新增加内容,因此已成为中考命题的亮点和热点.复习这部分内容时,必须进一步理解概率的概念和掌握概率的计算方法,密切联系现实生活,多做试验,留心身边的每一件事,把实际问题与理论知识结合起来考虑问题,体会概率在决策中的作用.中考内容要求了解事件的分类,理解概率的意义,知道通过大量重复实验时用频率可作为事件发生概率估计值,会用
Probability is a new addition to the new curriculum standards, so it has become a bright spot and a hot topic in the senior high school entrance examination test.When reviewing this part, we must further understand the concept of probability and the method of calculating the probability, closely connect with real life, do more experiments, Each side of the matter, the actual problems and theoretical knowledge combined to consider the problem, to understand the role of probability in decision-making.Paper content requires understanding of the classification of events to understand the significance of probability, knowing that through a large number of repetitive experiments with frequency as an event Occurrence probability estimates, will be used
