Here's a problem from my book that I just cannot solve:

An insurance company classifies drivers as low-risk, medium-risk, and high-risk. Of those insured, 60% are low risk, 30% are medium risk, and 10% are high risk. After a study, the company finds that during a 1-year period, 1% of the low risk drivers had an accident, 5% of the medium risk drivers had an accident, and 09% of the high risk drivers had an accident. If a drier is selected at random, find the probability that the driver will have had an accident during that year.

Ans: 0.03

What i tried doing was (0.01/0.6 * 0.05/0.3 * 0.09/0.1); looks like that's not the answer :(

Does anyone know how to solve this, and whether it's an independent or dependent event?

THANKS IN ADVANCE!
