How does the Joint Prob Calculator work?

P(A and B) = P(A) × P(B|A) (conditional) Then: P(A and B) = P(A) × P(B) (if independent) Then: Extends to 3+ events: P(A and B and C) = P(A) × P(B|A) × P(C|A and B) Then: Always ≤ minimum of individual probabilities.

Can you give an example of how to use the Joint Prob Calculator?

Example: Input P(A)*P(B) gives a result of 0.3*0.4=0.12.

Is the Joint Prob Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
