<--- Enter P(A | B)
<--- Enter P(B)
<--- Enter P(A | B')

How does the Bayes Rule Calculator work?

Calculates the conditional probabilities of (B given A) of 2 events and a conditional probability event using Bayes Rule
This calculator has 3 inputs.

What 3 formulas are used for the Bayes Rule Calculator?

  1. P(B | A) = P(A | B) x P(B)/(P(A | B) x P(B) + P(A | B') x P(B'))
  2. P(B') = 1 - P(B)
  3. P(A') = 1 - P(A)

What 3 concepts are covered in the Bayes Rule Calculator?

bayes rule
Probability of an event, based on existing preconditions of other events
a set of outcomes of an experiment to which a probability is assigned.
the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes
