1.本单元知识点概率是研究随机现象规律的学科,它为人们认识客观世界提供重要的思维模式和解决问题的方法,同时为统计学的发展提供了理论基础.由于概率与实际生活密切相关,它能极好地培养数学应用的意识.本单元的学习重点包括:(1)在具体情境中加深对随机现象的认识,进一步理解概率的意义和概率与频率的区别;(2)通过实例,了解两个互斥事件的概率加法公式;(3)通过实例,理解古典概型及其概率计算公式,并会用列举法计算一些随机事件的
1. The probability of knowledge point of this unit is a discipline that studies the law of random phenomena, which provides important thinking modes and solutions to people’s understanding of the objective world, and provides a theoretical basis for the development of statistics. Since the probability is closely related to real life , Which can well cultivate the awareness of mathematical applications.The learning focuses of this module include: (1) to deepen the understanding of stochastic phenomena in specific situations, to further understand the meaning of probability and the difference between probability and frequency; (2) , Understand the probability addition formula of two mutual exclusion events; (3) Through the example, understand the classical probability and probability formula, and will use enumeration method to calculate some random events
