Problem 5. In a population, the proportion of good and bad drivers is 2/3 and 1/ 3, respectively. In any given year, a good driver will have an accident with probability 1/4, and a bad driver with probability 3/4. A driver is selected at random from this population and observed for 3 years. This is similar to the 'tossing a randomly selected coin\" examples used in lecture. See pages 1316 of notes2.pdf anal pages 68 of notes3.palf. (a) (8%) What is the probability the driver has accidents in exactly 2 of these 3 years? (b) (8%) If the driver has accidents in exactly 2 of the 3 years, what is the probability the driver is bad
