An insurance company believes that people can be divided into two classes -- those that are accident prone and those that are not. Their 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 0.2 for a non-accident-prone person. Assume that 10 percent of the populations is accident prone.
