Work Step by Step

If two events are independent, then the occurrence of one of the events does not affect the probability that the other will occur. Contrarily, if two events are dependent, then the occurrence of one will affect the probability that the other event will occur. Independent events: The probability that a given coin will land on tails and the probability that a different coin will land on tails. Dependent events: The probability that the Boston Red Sox will win and the probability that I will be happy. (If the Red Sox win, then I am more likely to be in a better mood, for I am a Redsox fan. Thus, the occurrence of one event affects the probability of the other.)
