In the draw of the third card, this probability would be dependent upon the outcomes of the previous two cards. Independent events are events that do not affect the outcome of subsequent events. Given these events, the multiplication rule states the probability of occurrence of both events is found by multiplying the probabilities of each event. Two disjoint events can never be independent, except in the case that one of the events is null. Dependent events influence the probability of other events or their probability of occurring is affected by other events. Assuming that A and B are events with nonzero probabilities, P(A|B) = P(A) is actually mathematically. Two events are independent if the result of the second event is not affected by the result of the first event. Therefore, the first event will affect the results of the second event. From the Venn diagram P (X) can be written as: P . The probability of independent events occurring is found by multiplying the probability of the first event occurring by the probability of the second event occurring.
