Adults were randomly selected for a Newsweek poll, and they were asked if they “favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos.” Of the adults selected, 481 were in favor, 401 were op- posed, and 120 were unsure. Based on these results, find the probability that a randomly se- lected adult would respond in favor. Is it unusual for an adult to be in favor?
