8. Individual Problems 20-4 Suppose that every driver faces a 4% probability of an automobile accident every year. An accident will, on average, cost each driver $5,000. Suppose there are two types of individuals: those with $30,000.00 in the bank and those with $2,500.00 in the bank. Assume that individuals with $2,500.00 in the bank declare bankruptcy if they get in an accident. In bankruptcy, creditors receive only what individuals have in the bank. Assume that both types of individuals are only slightly risk averse. In this scenario, the actuarially fair price of full insurance, in which all damages are paid by the insurance company, is $ Assume that the price of insurance is set at the actuarially fair price. At this price, drivers with $30,000.00 in the bank likely v buy insurance, and those with $2,500.00 in the bank likely buy insurance. (Hint: For each type driver, compare the price of insurance to the expected cost without insurance.) Suppose a state law has been passed…

Among the 35,000 participants, 27,500 gain entry via the lottery. What percent of lottery applicants were selected for participation in the marathon? [Incidentally, I was not selected, but my odds of selection were better than in the prior year when 330,270 people entered the lottery. Due to the current cronavirus situation, the marathon scheduled for March 1, 2020was cancelled.] A. 90.62% B. 11.93% o C. 9.38% D. 88.07%

4. Claire is considering investing in a new business. In the first year, there is a probability of 0.2 that the new business will lose $10,000, a probability of 0.4 that the new business will break even ($0 loss or gain), a probability of 0.3 that the new business will make $5,000 in profits, and a probability of 0.1 that the new business will make $8,000 in profits. a. Claire should invest in the company if she makes a profit. Should she invest? Explain using expected values. b. If Claire's initial investment is $1,200 and the expected value for the new business stays constant, how many years will it take for her to earn back her initial investment?

When the true state of nature is S1, the research will accurately predict S1 60% of the time. When the true state of nature is S2, the research will accurately predict S2 80% of the time. What is the posterior probability of S1 given that the research predicts S1? Multiple Choice: 0.18 0.82 0.57 0.44 0.65
