初学概率的学生很快会对概率产生浓厚的兴趣,他们感到教师讲的都很有道理,都听得懂,但自己一拿到习题,却无从下手。这个现象表明:学生己感觉到周围有很多随机现象,但还未理解它们,无法把握住一个随机现象,更不知怎样去分析一个随机现象,怎样去思考一个概率问题。本文试图对这些问题提出一些想法,供初学者参考。
Students with probabilistic beginners will soon have a keen interest in probability. They feel that the teachers speak very well and they all understand it. But once they get the problem, they cannot start. This phenomenon shows that students have felt a lot of random phenomena around them, but they have not yet understood them, they cannot grasp a random phenomenon, and they do not know how to analyze a random phenomenon and how to think about a probability problem. This article attempts to put forward some ideas for these issues for reference by beginners.
