摘要
概率论是一门研究随机现象发生规律的学科,其中规律是通过计算事件发生的概率来衡量的,从而概率的计算问题变得尤为重要。解决该问题的方法多种多样,利用"古典概型"来计算随机事件的概率,是概率论的核心基础内容之一。"古典概型"虽然思想简单,但在应用时却常常出错。为了更好地理解"古典概型"方法以及准确快捷地利用它解决实际问题,通过实例对应用"古典概型"计算概率的方法进行剖析,总结出有助于理解以及合理应用"古典概型"方法的四个要点。
Probability is a discipline that studies the law of random phenomena,in which the law is measured by the probability of occurrence,so the problem of calculating the probability becomes very important and has many computing methods. Classical probability model,one of the core elements of the probability theory,is simple but often makes mistakes in the application. For this purpose,the paper analyses the probability calculated by using classical probability in illustrative examples and summarizes four main points that are helpful to understand and solve practical problems accurately.
