Bayes’ Theorem

In our example we have two events that satisfy the condition in the denominator, so we substitute for P(B) and get Bayes’ Theorem for a 2-event case.

P(A1|B)=

P(A1)*P(B|A1)/{P(A1)*P(B|A1)+P(A2)* P(B|A2)

Bring specific questions with you to class and we’ll look at more practice with Bayes’ Theorem.
