“概率与统计”是人们了解“不确定性”数学现象的重要工具 .现实社会生产、生活中 ,存在着大量的不确定性的数学问题 ,其中蕴含着确定性的结论 ,对于指导人们从事社会生产、生活具有十分重要的意义 .因此 ,“概率与统计”以近半个学期的学习内容进入了高中课本 ,占整个高中数? “Probability and statistics” is an important tool for people to understand the “uncertain” mathematical phenomenon. In the actual production and life of society, there are a large number of mathematical problems of uncertainty, which contain definitive conclusions and guide people to engage in society. Production and life have a very important significance. Therefore, “probability and statistics” has entered the high school textbooks for nearly half of the semester’s content, which accounts for the entire number of high schools.
