希尔伯特曾明确指出 :“数学科学是一个不可分割的有机整体 ,它的生命力正在于各个部分之间的联系 .”中学数学各分支内容之间同样也具有普遍的联系 .概率统计是新课程中的热点 ,以概率统计的观点来研究和处理其它数学分支的问题将别有一番情趣 .本文通过构造概率统计模型解几 Hilbert once pointed out clearly: “The science of mathematics is an inseparable organic whole. Its vitality lies in the connection between various parts.” There are also common connections between the various branches of middle school mathematics. Probability statistics are new. The hot topics in the course, the study and processing of other mathematics branches from the point of view of probability statistics will have some fun. This paper constructs a solution of the probability and statistics model.
