Probability Formula

Probability = Favorable Outcomes ÷ Total Outcomes

Probability measures the likelihood of an event occurring. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability values range from 0 to 1 and can also be expressed as percentages.

Example Calculation

Input: Favorable Outcomes = 2, Total Outcomes = 6

Output: Probability = 2/6 = 0.3333 = 33.33%
