Why or why not? [1] 530-611

Recently, Goran ran for president of the local school board. Of those who voted in the election, 80% had a high school diploma, and the other 20% did not. Goran got 70% of the vote of those with high school diplomas, while he got only 15% of the vote of those without high school diplomas. Let D denote the event that a randomly chosen voter (in the school board election) had a high school diploma and D denote the event that a randomly chosen voter did not have a high school diploma. Let V denote the event that a randomly chosen voter voted for Goran and V denote the event that a randomly chosen voter did not vote for Goran. Fill in the probabilities to complete the tree diagram below, and then answer the question that follows. Do not round any of your responses. (If necessary, consult a list of formulas.) (a) Fill in the missing probabilities. P(VD) = 0.7 P(DnV) = 0 P (D) = 0.8 Continue Submit Assignme Privacy Center | Accessibili (4¹) Ⓒ2022 McGraw Hill LLC. All Rights Reserved. Terms…
