Calculates the probability of intersection of two events: P(A ∩ B) = P(A) × P(B) for independent events, or given directly for dependent events.
P(A ∩ B) = P(A) × P(B) (if independent)
For independent events, intersection probability equals product of individual probabilities

About this calculator
Overview
Probability of Intersection Calculator evaluates Probability of Intersection for the math / probability library. Primary input cue: Probability of Event A [required]: Probability of event A (0 to 1). Method anchor: P(A ∩ B) = P(A) × P(B) (if independent). For independent events, intersection probability equals product of individual probabilities.
When to use
Use this page when you need probability of intersection from known inputs and want a transparent arithmetic or symbolic check.
Inputs explained
- Probability of Event A [required]: Probability of event A (0 to 1)
- Probability of Event B [required]: Probability of event B (0 to 1)
- Events are Independent [required]: Whether events A and B are independent
Formula / method
P(A ∩ B) = P(A) × P(B) (if independent). For independent events, intersection probability equals product of individual probabilities (calculator id: probability-of-intersection-calculator).
Worked example
Worked values: probA = 0.5, probB = 0.4, independent = True → intersectionProbability = 0.2
Interpreting results
Read the primary output as probability of intersection under the method on this page.
Assumptions
- The wired execution function for `probability-of-intersection-calculator` is the source of numerical behavior.
- Inputs for `probability-of-intersection-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless probability of intersection explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of probability of intersection.
- Edge cases outside the intended domain of probability of intersection may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for probability of intersection.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
