Fig 1 
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 sometime within a fixed one-year period 
with probability 0.6, whereas this probability is 0.2 for a person who is not accident 
prone. The company knows that 20 percent of the population is accident prone.  
Based on the given information, answer the following questions. 
 
 (i)what is the probability that a new policyholder will have an accident 
within a year of purchasing a policy? 
2 
 (ii) 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?
