 | | But with the first die, if 1 falls uppermost, clearly It rules out the possibility of 6 being uppermost, so the two Outcomes, 1 and 6, are mutually exclusive, One result directly affects the other. |
 | | In this case, the probability of throwing 1 or 6 with the first die is the sum of the two probabilities, 1/6 + 1/6 = 1/3. |
 | | When two events are mutually exclusive,(they can't happen at the same time) the probability of one or the other happening is the sum of the probabilities of each event. |
