Write out the probability statement for the following scenario: A factory has two assembly lines (A and B). Each day it randomly tests a certain number of parts. If the parts pass inspection, they go on in the assembly process, but if they don't pass the inspection they are labeled defective and put aside for further testing. A worker picks up a random part from the group set aside for further testing. What is the probability that part came from line A? 1) P(Defective and A) 2) P(A|Defective) 3) P(Defective or A) 4）P(Defective|A)
