由于随机事件的概率与现实生活密切相关,因而是高考必考内容之一.考查形式多以选择题和填空题为主.试题立足于教材,关注概念的应用,重在考查考生根据生活、生产等实际问题的情境分析问题、解决问题的能力.解决此类问题的关键是,要善于从普通语言中捕捉到有价值的信息,并将普通语言转化为数学语言,提高应用数学知识与方法解题的能力.重点难点重点:了解随机事件发生的不确定性和频率的稳定性;正确理解概率的意义;掌握概率在实际中的应用;概率的几个基本性质.
Because the probability of random events is closely related to real life, it is one of the contents of the college entrance examination.Experimental questions mainly focus on the multiple choice questions and fill in the blank questions.Test questions based on the textbook, attention to the application of the concept, focusing on test candidates according to life, production And other practical problems situation analysis, the ability to solve problems.The key to solve such problems is to be good at capturing valuable information from the ordinary language, and the ordinary language into a mathematical language to improve the application of mathematical knowledge and methodological solutions The key competencies Focus: to understand the uncertainty of random events and the stability of the frequency; the correct understanding of the meaning of probability; to grasp the probability of practical applications; several basic properties of probability.
