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)​.
