   Hi - could someone please tell me where I'm going wrong.
   
   I don't understand why A1 isn't also a correct option.
   
   Does A1 not simplify to
   
   P(B and Defect) / P(Defect)
   
   which is equal to
   
   P(B | Default) = P(B and Default) / P(Default) which is what we are looking for.
   
   Thanks in advance

   S2020 Q3i, it is A2 because of the data available to you in the table, in the table we have P(defective|made in factory B) and P(made in factory B).
