This calculator finds the probability of event A or B not occuring, occuring together or just one of them.
You need to provide the probability of A and B below and click the ‘Calculate’ button:
Probability that event A does not occur: P(A'): 0.50
Probability that event B does not occur: P(B'): 0.80
Probability that event A and/or event B occurs P(A∪B): 0.60
Probability that event A and event B both occur P(A∩B): 0.10
Probability that either event A or event B occurs, but not both: 0.50
