Card 1 of 20
The set of all possible outcomes is the [ ], usually written SSS.
A
The union, A∪BA\cup BA∪B.
B
If P(A)≠0P(A)\ne0P(A)=0, independence is equivalent to P(B∣A)=P(B)\boxed{P(B\mid A)=P(B)}P(B∣A)=P(B).
C
The set of all possible outcomes is the sample space, usually written SSS.
D
Events AAA and BBB are independent when P(A∩B)=P(A)P(B)\boxed{P(A\cap B)=P(A)P(B)}P(A∩B)=P(A)P(B).
