The probability that a bus chosen at random is ready for service and has a working radio is 67%.
The probability that a bus chosen at random is ready for service is 84%.
Therefore, the probability that a bus chosen at random has a working radio given that it is ready for service is:
(Probability of ready bus with radio) / (Probability of ready bus)
= 67% / 84%
= 79.8%
Therefore, the answer is 79.8%.
