Calculate probabilities for single, independent, dependent, mutually exclusive, and complementary events with step-by-step explanations
For a single event:
P(A) = Favorable Outcomes / Total Outcomes
P(A) = 3 / 6
P(A) = 1/2 = 0.5 = 50%
This free probability calculator helps you determine the likelihood of an event occurring using standard probability formulas. Whether you’re working with single or multiple events, it gives you the tools to solve your probability questions quickly and clearly.
Select the type of probability scenario, input your values, and the calculator shows you the result as both a fraction and percentage, with step-by-step breakdowns and explanations.
