That might be a little contrived in the case of a personnel database, but it's not at all contrived if our database contains "partial license plates, as reported by eyewitnesses to a crime" There, knowing that "the last digit was either a 3 or an 8" is both entirely within the realm of possibility, but it might be a crucial fact to recall in order to make a timely arrest.
