Roads A, B, and C are the only way to escape from a certain provincial prison. Prison records show that, of the prisoners who tried to escape, 17% used road A, 13 % used road B, the remainder used road C. The records also indicate that 72 % of those who tried to escape using road A were captured. 62 % of those using road B were captured, and 21% of those using road C were captured. Use four decimals in your answers. (a) What is the probability that a prisoner escaping from this provincial prison is not captured? 0.65 (b) What is the probability that a captured prisoner used road A in their escape attempt? (c) What is the probability that a prisoner who didn't get captured has used road C?
