Question

The prior probabilities for events A1 and A2 are P(A1) = 0.35 and P(A2) = 0.55. It is also known that P(A1A2) = 0. Suppose P(B | A1) = 0.20 and P(B | A2) = 0.05. If needed, round your answers to three decimal digits.

 

(a) Are A1 and A2 mutually exclusive?
  - Select your answer -YesNoItem 1
  Explain your answer.
  The input in the box below will not be graded, but may be reviewed and considered by your instructor.
 
 
 
   
(b) Compute P(A1B) and P(A2B).
 
P(A1 ∩ B) =  
P(A2B) =  
   
(c) Compute P(B).
  P(B) =
   
(d) Apply Bayes’ theorem to compute P(A1 | B) and P(A2 | B).
 
P(A1 | B) =  
P(A2 | B) =
