事件及其概率
设<Object: word/embeddings/oleObject1.bin>
为三个事件，试写出下列事件的表达式：
<Object: word/embeddings/oleObject2.bin>
都不发生；
(2)<Object: word/embeddings/oleObject3.bin>
不都发生；
(3)<Object: word/embeddings/oleObject4.bin>
至少有一个发生；
(4)<Object: word/embeddings/oleObject5.bin>
至多有一个发生。
解：(1)<Object: word/embeddings/oleObject6.bin>
<Object: word/embeddings/oleObject7.bin>
<Object: word/embeddings/oleObject8.bin>
<Object: word/embeddings/oleObject9.bin>
设<Object: word/embeddings/oleObject10.bin>
为两相互独 ...
