In a Bruskin-Goldring Research poll, respondents were asked how a fruitcake should be used. One hundred forty-five respondents indicated that it should be used for a doorstop, and 800 other respondents cited other uses, including birdfeed, landfill, and a gift. If one of these respondents is randomly selected, what is the probability of getting someone who would use the fruitcake as a doorstop?
