What is meant by conditional probability? State the formula for finding conditional probability. Is the probability of “A given B” the same as the probability of “B given A?” Explain. In general (whether events are independent or not), what is the formula for finding ? Explain the difference between the Multiplication Rule for ...

Rearranging the Conditional Probability Formula, we get: ... Independent Events: Events A and B are independent if the occurrence of B doesn’t affect the probability that A occurs (and vice versa). That is, A and B are independent if and only if. P(A | B) = P(A).

We can use the conditional probability formula to define independence: Two events are independent iff (if and only if), And . This result tells us that the two rolls of the die are independent events. Multiplication Rule for Probability: The probability that two events A and B occur is given by: If the two events A and B are independent, we may ...
