3. Ann and Bob have different preferences for risk of injury on the job: Ann is less willing to take on risk of injury on the job than is Bob (although both dislike risk). a. On a graph with the probability of injury on the job on the x-axis and the wage level on the y- axis, plot two indifference curves (labeled UA and U13) illustrating these differences in preferences. Explain clearly what it is about the indifference curves that indicates that Ann is less willing to take on risk than is Bob. b. Suppose Chris does not care about the risk of injury on the job. In other words, he does not seek to limit risk or to expose himself to risk. On a new graph, draw several of Chris's indifference curves. Include an arrow on the graph showing which direction is associated with higher levels of utility
