A fair coin is flipped twice. H is recorded for heads and T for tails after each flip. Let Event A be heads on the first attempt and Event B be heads on the second attempt.

Which statement about the conditional probability is true?

Choices

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(B)/P(A) when two events are 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.

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