13. (a) Define dependent and independent events. If A and B are independent eventsthen show that there complementary events not A and not B are alsoindependent. |

Answer» Two events areindependentif the result of the second event is not affected by the result of the first event. IfAAandBBare independent events, theprobabilityof both events occurring is the product of the probabilities of the individual events.Two events aredependentif the result of the first event affects the outcome of the second event so that the probability is changed. In the above example, if the first marble is not replaced, the sample space for the second event changes and so the events are dependent. The probability of both events occurring is the product of the probabilities of the individual events |
