A and B are two events. The notation for conditional probability is P(B|A) . Which statement about the conditional probability is true?

The conditional probability of event B given event A is P(B|A)=P(A)P(B) when two events are independent.
The conditional probability of event B given event A is P(B|A)=P(B)P(A) when two events are independent.

The conditional probability of event B given event A is P(B|A)=P(B) when two events are not independent.

The conditional probability of event B given event A is P(B|A)=P(A and B)P(A) when two events are not independent.
