The probability that a bus is ready for service and has a working radio is 59%.
The probability that a bus is ready for service is 76%.
To find the probability that a bus has a working radio given that it is ready for service, we use the formula for conditional probability:
P(working radio | ready for service) = P(working radio and ready for service) / P(ready for service)
P(working radio | ready for service) = 0.59 / 0.76 = 0.7763
Rounded to the nearest tenth of a percent, the probability that a bus chosen at random has a working radio given that it is ready for service is 77.6%.
Therefore, the correct response is 77.6%.
