A quality control inspector knows that the items she inspects have at most two types of defects: Type A and Type B. Past experience has shown that P(A)=4.1%, P (B)=4%, and P(A and B)=1.45%. If an item is selected at random what is the probability that it has a defect type A but it does not have a defect type B? Round your answer to three decimal places.
