1.概率论研究的对象我們知道,数学是研究客观世界的量的关系的科学。数学的每个分支都是直接或間接地由于客观生产实践的需要而产生的,无論是它的基本概念、內容和方法,都必須正确地反映和研究客观現象的某种量的規律。那末,概率論所研究的,究竟是哪一类量的規律呢? 自然科学在观察和实驗的基础上所确立的最簡单的規律性是指出我們所研究的事件必然发生或必然不发生的条件;換句話說,这些条件可以表成以下两种模型中的一种:
1. The object of the study of probability theory We know that mathematics is the science of the relationship between the quantity of the objective world. Each branch of mathematics is produced directly or indirectly due to the need of objective production practices. Regardless of its basic concepts, contents, and methods, it must accurately reflect and study the laws of certain quantities of objective phenomena. Then, what type of quantitative law is the study of probability theory? The simplest regularity that natural science establishes on the basis of observation and experiment is to point out that the events we studied must happen or must not happen. Conditions; in other words, these conditions can be expressed in one of the following two models:
