- O Question 12 <. A CBS News poll involved a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results are shown in the table below. %3D better same worse Republican 38 104 44 Democrat 12 87 137 none 21 90 118 If we randomly select one of the adults who participated in this study, compute: (round to four decimal places) a. P(Republican) = b. P(better) = %3D c. P(better | Republican) = С. %3D d. P(Republican | better) = %3D e. P(Republican and better) Submit QuestionQuestion 22 A die is rolled. If an odd number turns up, we win an amount equal to this number; if an even number turns up, we lose an amount equal to this number. For example, if a two turns up we lose 2, and if a three comes up we win 3. What is the average profit you can make if you participate this game? Average profit is Blank 1 Round off your final answer into four decimal places. #.#### Blank 1 Add your answerAn ASU student makes a New Year resolution to shed a few pounds by going to the gym and eating right.
