To find P(C | A)
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\%}
