An insurance company believes that people can be divided into two classes: those who are accident prone and those who are not. The company's statistics show that an accident-prone person will have an accident at some time within a fixed 1-year period with probability 0.3, whereas this probability decreases to 0.1 for a person who is not accident prone. We assume that 20 percent of the population is accident prone. Suppose that a new policyholder has an accident within a year of purchasing a policy. What is the probability that he or she is accident prone?
