Understanding Mutually Exclusive Events

In probability theory, two events are mutually exclusive if they cannot occur at the same time. If event A and event B are mutually exclusive, the probability of either A or B occurring is the sum of their individual probabilities.

Formula: For mutually exclusive events \(A_1, A_2, ..., A_n\), the probability of any one of them occurring is:

$$P(A_1 \cup A_2 \cup ... \cup A_n) = P(A_1) + P(A_2) + ... + P(A_n)$$

Example: Consider rolling a standard six-sided die. The events "rolling a 2" and "rolling a 5" are mutually exclusive because you cannot roll a 2 and a 5 at the same time. If the probability of rolling a 2 is 1/6 and the probability of rolling a 5 is 1/6, then the probability of rolling either a 2 or a 5 is \(1/6 + 1/6 = 2/6 = 1/3\).

This calculator helps you quickly determine the combined probability when dealing with multiple mutually exclusive events. Simply input the individual probabilities, and let the tool do the rest!
