This Bayes Theorem calculator will help you determine the probability of an event based on prior knowledge of conditions related to the event.
Bayes Theorem Calculator
How to Use the Calculator
Enter the values for the Prior probability (P(A)), the Probability of B given A (P(B|A)), and the Probability of B (P(B)). After filling in the values, click on the “Calculate” button to get the result for P(A|B), the probability of A given B.
How the Calculator Works
The calculator uses Bayes’ theorem, which is a way to find a probability when you know certain other probabilities. The formula looks like this:
P(A|B) = [P(B|A) * P(A)] / P(B)
The result will be displayed in the ‘Result’ field.
Limitations of the Calculator
This calculator assumes the entered probabilities are valid and within the range 0 to 1. It does not validate the coherence or consistency of the probability values in the context of the specific problem you are trying to solve. Always ensure the values entered make logical sense for the situation you are analyzing.
