A car insurance company wants to implement experience related premiums, and asks you to estimate the % of total accidents in the last year caused by the following age groups. For example: 10%, 20%, 70% (a, b, c):
(a) 1 year’s experience (average under 20 years old)
(b) 15 years’ experience (average age 35 years old)
(c) 30+ years’ experience (average age 50 years old)
