5、判断 设A，B是任意两事件，若AB=phi，且overline(A)B=phi，则overline(A)=B.

5.设事件A,B满足条件 (AB)=P(overline (A)B), 且 (A)=p, 则 P(B)=-|||-__

设A，B为两事件，则(A∪B)(overline(A)∪overline(B))表示( )A. 必然事件B. 不可能事件C. A与B恰有一个发生D. A与B不

设事件A与事件B互不相容，则（ ）。A.(overline (A)overline (B))=0-|||-__ B.(overline (A)ov

设事件A，B相互独立，且P（overline(A)∩overline(B)）=(1)/(9)，P（Aoverline(B)）=P（overline(A)B），则

图-175 设事件A、B相互独立, (A)gt 0, (B)gt 0, 则 ()-|||-A、 =phi B、 (A-B)=P(A)cdot P(overli

4.设A,B为两个随机事件,且 (A)=0.7, (A-B)=0.3, 则 (overline (AB))= __

5.设A,B,C为三个随机事件,且 (overline (A)cup overline (B))=0.8 (overline (A)cup overline (

2.设A,B为二随机事件,则 (ABcup Aoverline (B))(Acup overline (A)overline (B))= ()-|||-(A)A

2.设A,B为二随机事件,则 (ABcup Aoverline (B))(Acup overline (A)overline (B))= ()-|||-(A)A

1.设 (AB)=P(overline (A)overline (B)), 且 (A)=p, 求P(B).
