据悉,在新近修订的高中数学课程内容草案中,“统计与概率”大单元的分量比以前有所加强,这更激发笔者对此单元的探源研究.1概率和期望的概念史话概率和期望是“统计与概率”大单元的两个核心概念,其萌发的源头至少可以追索到15世纪意大利数学家帕西奥里(L.Pacioli,1445~1514)在1494年出版的著作《算术、几何、比及比例全书》中记载着的一个问题——例1甲、乙两人在一次比赛前约定谁先赢6次才赢得
It is reported that in the newly revised draft content of the high school mathematics curriculum, the component of the unit of “statistics and probability” is stronger than before, which stimulates the author’s exploration of the source of the unit.1 The concept of probability and expectation The probability of history And expectations are two core concepts of the “statistics and probability” unit, whose germination can be traced at least to the 15th century Italian mathematician Parsoli (L.Pacioli, 1445-1514) published in 1494 One of the problems recorded in the book Arithmetic, Geometry, Ratio, and Proportionality - Example 1 A, B both won prior to a match who won six first
