How do you measure the chance of something happening?

To measure the chance of something happening, you typically use probability, which quantifies the likelihood of an event occurring. This is expressed as a ratio of the number of favorable outcomes to the total number of possible outcomes, often represented as a fraction, decimal, or percentage. For example, if there are 3 favorable outcomes and 10 possible outcomes, the probability is 3/10 or 30%. Additionally, statistical methods and historical data can help refine these estimates in real-world scenariOS.
