Of the Democrats, 18 declared themselves gun owners; of the Republicans, 27 of them declared themselves gun owners; none of the Independents owned guns. If a senator participating in that survey was picked at random and turned out to be a gun owner, what was the probability that he or she was a Democrat? (Round your answer to four decimal places.)
