How to Use the Bayes Theorem Calculator?

The procedure to use the Bayes theorem calculator is as follows:

Step 1: Enter the probability values and “x” for an unknown value in the respective input field

Step 2: Now click the button “Calculate x” to get the probability

Step 3: Finally, the conditional probability using Bayes theorem will be displayed in the output field

What is Meant by the Bayes Theorem?

In mathematics, Bayes theorem provides a formula to calculate the conditional probability for the given event. It defines the probability of an event based on the prior knowledge of conditions which might be related to the event. The formula obtained from Bayes theorem is given below:

 P(A|B) = [P(A) P(B|A)]/P(B)

Where

P(A) – Probability of event A

P(B) – Probability of event B

P(A|B) – Probability of A given B

P(B|A) – Probability of B given A
