From a survey of 20,000 eligible voters, it was found that 13200 were employed, 5000 were unemployed and the rest were self-employed. Furthermore, it was found that 34%, 57%, 73% of eligible voters who were employed, unemployed and self-employed respectively voted in the last presidential election. a) If a person who voted in the last election is selected at random, what is the probability that he/she was self-employed? b) What is the probability of an eligible voter not being unemployed given that he/she did not vote in the last election?
