Case Study 01:
(14)
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
Solution: Let E1 = The policy holder is accident prone. E2 = The policy holder is not accident prone. E = The new policy holder has an accident within a year of purchasing a policy.
(i) what is the probability that a new policyholder will have an accident within a year of purchasing a policy?
Ans: P(E) = P(E1) × P(E/E1) + P(E2) × P(E /E2)
= 20/100 × 6/10 + 80/100 × 2/10 = 7/25
(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?
Ans: By Bayes’ Theorem, P(E1/E) = P(E1) × P(E/E1) / P(E)
= 20/100 × 6/10 / 280/1000 = 3/7
