Web5 jan. 2024 · Mutually Exclusive Events: P (A∪B) = P (A) + P (B) If A and B are not mutually exclusive, then the formula we use to calculate P (A∪B) is: Not Mutually Exclusive Events: P (A∪B) = P (A) + P (B) - P (A∩B) Note that P (A∩B) is the probability that event A and event B both occur. The following examples show how to use these formulas in practice. WebThe probability of any one of them is 1 6 Probability In general: Example: the chances of rolling a "4" with a die Number of ways it can happen: 1 (there is only 1 face with a "4" on it) Total number of outcomes: 6 (there are 6 faces altogether) So the probability = 1 6 Example: there are 5 marbles in a bag: 4 are blue, and 1 is red.
