WebTwo events A and B are mutually exclusive (disjoint) if they cannot both occur at the same time. That is, event A can occur, or event B can occur, or possibly neither one – but they cannot both occur at the same time. You can tell that two events are mutually exclusive if the following equation is true: P (AnB) = 0. WebMar 14, 2024 · In probability, two events are independent if the outcome of one event does not influence the outcome of the second event. A good example of a pair of independent events is when we roll a die and then flip a coin. The number showing on the die has no effect on the coin that was tossed. Therefore these two events are independent.
