1.If A and B are 2 independent events and P(A)=0.9 and P(not B)=0.2,find P(not A or B).
2.Consider 2 independent events A and B.If P(A)=0.85 and P(B')=0.35,find P(A' and B).
英语翻译1.If A and B are 2 independent events and P(A)=0.9 and P
A B是2个独立事件,P(A)=0.9,P(B拔)=0.2,求P(A拔 或 B)
P(A拔 U B)=1-0.9×0.2=0.82
考虑2个独立事件A B,P(A)=0.85,P(B拔)=0.35,求P(A拔 与 B)
P(A拔 与 B)=(1-0.85)×(1-0.35)=0.0975
