Probability Calculator
Find the probability of an event from favorable and total outcomes.
Find the chance of an event when all outcomes are equally likely.
The math behind it
P(event) = favorable outcomes ÷ total outcomes. The complement (NOT the event) is 1 − P.
Worked example
Rolling a 4 on a die → 1 ÷ 6 = 16.67%.
FAQ
Can probability exceed 1?
No — it ranges from 0 (impossible) to 1 (certain), i.e. 0% to 100%.
