Probability Calculator
Calculate simple probability, complements, independent events, unions, and conditional probability.
How to use the tool
Enter the requested values and choose a mode or operation when needed. Fields start empty so results always reflect your own data.
One favorable outcome among six possible equals 1/6, 0.1666…, or 16.66…%.
Formula and method
The two-event mode explicitly states independence; it does not infer it from external data.
P(A)=favorables/posibles · P(A|B)=P(A∩B)/P(B)
