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)*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.
