What formula is used to calculate the probability of an event occurring?

• A. Number of ways it can happen multiplied by Total number of outcomes
• B. Number of ways it can happen divided by Total number of outcomes
• C. Total number of outcomes divided by Number of ways it can happen
• D. Number of outcomes minus ways it can happen

Answer: (B)

The formula to calculate the probability of an event occurring is based on the ratio of favorable outcomes to the total number of possible outcomes. Specifically, the probability is determined by dividing the number of ways the event can occur by the total number of outcomes. This method reflects the fundamental principle of probability: it quantifies the likelihood of an event happening within a defined sample space. By using this ratio, one can effectively express the chance of a specific outcome occurring, which is foundational in probability theory. Understanding this concept is essential not only for academic purposes but also for practical applications across various fields, including statistics, gaming, and risk assessment. This approach helps in making informed decisions based on the likelihood of different events occurring.
