To find P(C | A) , the probability that a new driver has taken the course given that they had an accident, we use Bayes' theorem:

P(C | A) = \frac{P(A | C) \times P(C)}{P(A)}

Given:
- P(A | C) = 0.15
- P(C) = 0.80
- P(A) = 0.20

Substitute the values into the formula:

P(C | A) = \frac{0.15 \times 0.80}{0.20} = \frac{0.12}{0.20} = 0.60

Therefore, the probability that a new driver has taken the course given that they had an accident in their first year is \boxed{60\%} .
