App description

Joint probability of multiple events

If the two events A and B occur in a single performance experiment, this is called the intersection or joint probability of A and B, labeled PP(A n B). If two events, A and B, are independent, they can be joint probabilities from formulas

P(A n B) = P(A) P(B)

P(A)+P(A')=1，P(B)+P(B')=1

Usage example

Input data: impossible result -n: 20; number of events did not occur n (A): 10; number of events did not occur n (B): 12   Output: P(A): 0.5; P(A'): 0.5; P(B): 0.6; P(B'): 0.4; P(A n B) probability of multiple events 0.3; P(AUB) Mutual exclusion event probability 0.8; P(A | B) Conditional probability: 0.5
