About Bayes' Theorem Calculator

The Bayes' Theorem Calculator provides a helpful way to determine conditional probabilities using the Bayes' Theorem formula in the format P(A|B)=(P(A)*P(B|A))/P(B).

You are initially requested to input "What is the probability of:" (event A occurring)

"Given that:" (event B has occurred)

The calculator then populates Bayes' Theorem with this information to provide a clear understanding of your problem.

The calculator then asks for the following probability percentages:

P(A)%
P(B|A)%
P(B)%

The calculator then calculates the Bayes' Theorem results.

The calculator also calculates a table of observation percentages that helps with understanding the overall problem structure. To help verify results, the calculator provides a detailed calculation of the Bayes' Theorem using the included Table of Observation Percentages.

Finally, sample problems are provided to assist you with setting up your problem and input percentages.
