概率知识引入高中数学教材,是新课程的一个亮点,它与立体几何交汇的综合问题,以其新颖性、综合性而“闪亮登场”,这正好体现了高考能力立意及在知识网络交汇点处设计命题的精神.本文举例说明概率与立体几何的交汇与融合,旨在使学生养成概率与立体几何结合的意识,掌握运用的方法
The introduction of probabilistic knowledge into high school mathematics textbooks is a bright spot of the new curriculum. Its comprehensive problem of intersection with three-dimensional geometry is “brilliant appearance” with its novelty and comprehensiveness. This just reflects the college entrance examination ability and the intersection of knowledge networks. The spirit of designing propositions. This article illustrates the convergence and integration of probabilistic and solid geometry. It aims to enable students to develop the awareness of combining probabilistic and solid geometry and master the methods used.
