A dashboard flags policies with either an address mismatch A or a prior-carrier mismatch B. Current data show P(A) = 0.5000, P(B) = 0.3900, and P(A and B) = 0.2200. A manager reviews only files with at least one mismatch. For one reviewed file, what is the probability both mismatches are present A file-control value of 8007 is recorded but is not used in the calculation?
