9. The number of responses to a survey are shown in the Pareto chart. The survey asked 985 adults how they would grade the quality of their public schools. Each person gave one response. Find each probability. (a) Randomly selecting a person from the sample who did not give the public schools an A (b) Randomly selecting a person from the sample who gave the public schools a grade better than a D (c) Randomly selecting a person from the sample who gave the public schools a D or an F (d) Randomly selecting a person from the sample who gave the public schools an A or B (a) The probability that a randomly selected person did not give the public schools an A is (Round to three decimal places as needed.) (b) The probability that a randomly selected person gave the public schools a grade better than a D is (Round to three decimal places as needed.) (c) The probability that a randomly selected person gave the public schools a D or an F is (Round to three decimal places as needed.) (d) The probability that a randomly selected person gave the public schools an A or B is (Round to three decimal places as needed.)
