How do you represent the probability of an event?

The correct representation of probability is provided by stating that probability is equal to the number of favorable outcomes divided by the total number of outcomes. This formula captures the fundamental concept of probability, which measures the likelihood of a specific event occurring relative to all possible events.

When calculating probability, it is essential to first determine the total number of possible outcomes in the sample space. This reflects all the events that can happen in a given scenario. The number of favorable outcomes refers only to the specific outcomes that align with the event of interest. By dividing the number of favorable outcomes by the total number of outcomes, you obtain a value between 0 and 1, where 0 indicates that the event cannot occur, and 1 indicates that the event is certain to occur.

This concept is foundational in probability theory and is used in a variety of contexts, from simple games of chance to complex statistical models. The other formulations provided do not correctly convey the relationship between favorable outcomes and total outcomes necessary to determine the probability of an event accurately.
