概率与统计是2004年人教版及新课标各版本中的新增内容,能有效考查学生运用所学数学分析处理实际问题的能力,因而它已取代了多年中的传统数学应用题.2007年全国及各省市的19份高考试卷中,都考查了概率内容,其中16份试卷还特别考查了分布列、期望等相关知识.本文以2007年高考题为例,分类例析考查内容,指导复习,以利备考.
Probability and statistics are the new contents of the 2004 edition of the People’s Education Press and the new curriculum standard. They can effectively examine the students’ ability to use the mathematical analysis they have learned to deal with practical problems. Therefore, it has replaced many years of traditional mathematics applications. 2007 In the 19 exam papers of the whole country and provinces and cities, the probabilistic content was examined. Among them, 16 papers also examined the relevant knowledge of distribution columns, expectations, etc. This article takes the 2007 college entrance examination question as an example to classify and analyze the contents of the examination. Review to prepare for the test.
