Calculating the Probability of a Single Event

In probability, calculating the likelihood of a single event occurring is essential. The formula to determine the probability of an event is:

[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} ]

In simpler terms, it's the number of desired outcomes divided by the total outcomes. For instance, when rolling a fair six-sided die, the probability of getting a 4 is 1/6, as there is 1 favorable outcome (rolling a 4) out of 6 possible outcomes (rolling a number from 1 to 6).

Understanding this basic concept lays a solid foundation for further probability calculations.
