Given the following data answer the question that follows:

Year	Number of cars	Number of accident	Monetary loss
1	10	2	4,600
2	12	2	4,800
3	14	3	5,396
4	16	3	5,600
5	20	3	5,500

1. What is the probability that the firm will experience an accident next year?
2. What is the probability that the firm will suffer some monetary loss next year?
3. What is the probability that the firm will suffer losses totaling Birr 10,000 or more?
4. What is the maximum probable loss ignoring losses with less than 20%
5. Determine the standard deviation of loss.
6. What is the expected number of accident?
7. What is the expected monetary loss?
8. Calculate the risk related to the mean
9. Interpret your result in question number 9 Given one standard deviation, how many additional cars should the firm have in order to reduce the risk relative to the mean determined in (9) above by 20%?, if the distribution is approximated to normal.
