A company that manufactures video cameras produces a basic model and a deluxe model. Over the past year, 47% of the cameras sold have been of the basic model. Of those buying the basic model, 32% purchase an extended warranty, whereas 42% of all deluxe purchasers do so. If you learn that a randomly selected purchaser has an extended warranty, how likely is it that he or she has a basic model? (Round your answer to four decimal places.)
