Find the probability that the number of adults who say they are more likely to make purchases during a sales tax holiday is (a) exactly two, (b) more than two, and (c) between two and ve, inclusive. 2) = D (Round to the nearest thousandth as needed.) (c) P(2 5x5 5) = D (Round to the nearest thousandth as needed.)
