Probability Calculator
A powerful and intuitive tool designed to compute various probability scenarios for two independent events. Whether you’re a student, researcher, or data analyst, this calculator helps you quickly determine probabilities such as unions, intersections, complements, and more—all with just a few inputs.
Key Features:
✅ Basic Probability Calculator – Enter the probabilities of two events (A and B) to instantly compute:
-
P(A’) – Probability of A not occurring
-
P(B’) – Probability of B not occurring
-
P(A∩B) – Probability of both A and B occurring
-
P(A∪B) – Probability of A or B or both occurring
-
P(AΔB) – Probability of either A or B but not both occurring
-
P((A∪B)’) – Probability of neither A nor B occurring
-
P(A but not B) & P(B but not A)
✅ Advanced Probability Solver – Provide any two known values (e.g., P(A) and P(A∩B)) to automatically calculate all other probabilities with step-by-step explanations.
