本文将叙述用几何方法定义随机事件的概念和证明概率论中一些定律盼教学经验。我们不追求所述的经验充满新奇,但这种方法将引起教师的兴趣。 用几何方法叙述概率论一系列选修课教学法的价值在于它的直观性。由于下列诸原因,直观性将促使选修课教学成功。第一,直观性 This article will describe the concept of defining random events using geometric methods and prove that some of the laws in probability theory look forward to teaching experience. We do not pursue the described experience full of novelty, but this method will arouse teachers’ interest. The use of geometric methods to describe probability theory The value of a series of elective teaching methods lies in its intuitiveness. Due to the following reasons, intuition will promote the successful teaching of elective courses. First, intuitive
