随机事件与概率是概率论的入门知识,必须牢固掌握,才能为概率论的学习铺平道路。由于概率论是研究随机现象的统计规律的科学。它是数学中最活跃的分支,与描述确定性现象的数学相比,显然有它的特点。因此,我们在教 Random events and probabilities are introductory knowledge of probability theory and must be firmly mastered in order to pave the way for the study of probability theory. Because probability theory is the science of studying the statistical laws of random phenomena. It is the most active branch of mathematics. Compared with mathematics that describe deterministic phenomena, it clearly has its characteristics. So we are teaching
