Question 9
The number of responses to a survey are shown in the Pareto chart. The survey asked 1005 U.S. adults what they feel is the biggest problem with movies. Each person gave one response. Find the probability that a randomly selected person from the sample feels the biggest problem with movies is not both that movies have too much violence or that the tickets cost too much. This means that you are looking for the adults who did not say these two responses. Answer should be rounded to three decimal places.
