(Round your answer to four decimal places.) (b) What is the probability that a respondent 30+ years of age thinks that global warming will not pose a serious threat during his/her lifetime? (Round your answer to four decimal places.) (c) For a randomly selected respondent, what is the probability that a respondent answers yes?
