摘　　要：从几何的角度,揭示边缘分布条件分布的几何意义,浅显易懂,帮助学生深入正确理解定义所隐含的内容,同时,进一步推广了边缘分布和条件分布.By revealing the geometrical meaning of these distributions, this paper is to assist students progressively and appropriately grasp the meaning and ramification of these two distributions. In addition, this paper has also further expanded the scope of the marginal and conditional distributions.
