In a survey of 1000 eligible voters selected at random, it was found that 100 had a college degree. Additionally, it was found that 70%of those who had a college degree voted in the last presidential election, whereas 57% of the people who did not have a collegedegree voted in the last presidential election. Assuming that the poll is representative of all eligible voters, find the probability that aneligible voter selected at random will have the following characteristics. (Round your answers to three decimal places.)(a) The voter had a college degree and voted in the last presidential election.0.07(b) The voter did not have a college degree and did not vote in the last presidential election.0.03(c) The voter voted in the last presidential election.0.52(d) The voter did not vote in the last presidential election,0 577

The tree diagram for the following data is given as,
