Suppose the quality of a driver is characterized by a random variable x. A higher value of x indicates a better driver and the probability of accident is lower. x is uniformly distributed between 0 and 1. Suppose the probability of having a traffic accident is 0.05 0.04x. For example, if a driver has x = 0.2, the probability of having a traffic accident is 0.05 0.04 0.2 = 0.042. If the traffic accident happens, the loss is 1000. All people have an intiail wealth of 1200
