A bag of candy contains only nut chewies and marshmallow delights. there are twice as many nut chewies as marshmallow delights. ther nut chewies are either peanut or cashew and there are 1/3 as many cashew chewies as there are peanut chwies. if Julie selects on piece of candy at random, what's the probability that she picks a cashew chewy.?
