The method for calculating probability involves determining the likelihood of a specific outcome occurring in relation to all possible outcomes. To find the probability of an event, you take the number of favorable outcomes for that event and divide it by the total number of possible outcomes in the sample space. This ratio provides a measure of how likely the event is to occur, expressed as a fraction, decimal, or percentage.

For example, if you are rolling a fair six-sided die and want to find the probability of rolling a 3, there is one favorable outcome (rolling a 3) and a total of six possible outcomes (1 through 6). Thus, the probability of rolling a 3 is 1/6. This approach applies broadly across various probability scenarios, making it a foundational principle in both theoretical and experimental probability.

The other methods listed do not accurately represent the standard approach to calculating probability. Focusing solely on successful events without considering the total possible outcomes does not yield a fraction or probability value. Similarly, multiplying total successes by possible events does not align with the definition of probability, as it does not create a ratio of the specific outcome's chances to all possible outcomes. Lastly, merely adding outcomes together fails to provide a meaningful measure of likelihood without the
