WebbSolution: To find: The probability of getting a 2 or 3 when a die is rolled. Let A and B be the events of getting a 2 and getting a 3 when a die is rolled. Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0. Using the P (A∪B) formula, Webb0.3 + 0.12 = 0.42 probability of being a Goalkeeper today (That is a 42% chance) Check One final step: complete the calculations and make sure they add to 1: 0.3 + 0.3 + 0.12 + 0.28 …

General addition rule applies to any additional events. You can use it for both disjoint events and non-disjoint events where two events are mutually exclusive.

The outcome of the first roll does not change the probability for the outcome of the second roll. To show two events are independent, you must show only one of the above conditions.
