摘要
为揭示事件独立性的本质,从独立性的定义出发,先对古典概型场合展开讨论,得出两事件相互独立的一个充要条件.而后将结论推广至一般概率空间的场合,并基于所得结论给出一种用于构造独立随机变量序列的具体方法.
To reveal the essence of the independence of events,this paper started with the discussion from thedefinition of independence,and a necessary and sufficient condition of independence is given under the occasion ofclassical probability model. Then the conclusion is extended to the general probability space. Furthermore,basedon the conclusion,a method for constructing a sequence of independent random variables is given.
