Mutually Exclusive And Independent Events

Mutually exclusive events: The two events A & B are said to be mutually exclusive events when they cannot happen at the same time. Thus, A & B has no intersection area since they are not occurring at the same time. P(AΠB) = P(AB) = 0 where P(AΠB) is the probability of A intersection B and it is same as the probability of A multiplied by B, P(AB). In dependent events: The two events A & B are said to be independent events when the occurrence of one event does not influence the occurrence of other event. In this case, P(A Π B) = P(AB) = P(A)*P(B), that is, the probability of A & B is the probability of A multiplied by the probability of B. Difference between mutually exclusive events and independent events: One difference is as we have seen above, if A & B are mutually exclusive, the probability of their intersection is zero. P(AB) = 0 and  if they are independent, P(AB) = P(A)*P(B). The other difference can be seen fro
