摘要
从事件型全概公式出发,通过条件期望的定义及其重要性质推导出关于连续型随机变量的全概公式形式,并给出它在概率计算中的应用.
Starting from the total probability theorem of event type, the paper has deduced the total probability theorem of continuous random variable from the definition and important properties of conditional expectation, and illustrated its application in the probability calculation.
