The probability that a bus chosen at random has a working radio given that is it ready for service is 79.8%

How to determine the probability?

Represent the events with:

  • A represents Ready for service
  • B represents Has a working radio

So, we have:

P(A) = 84%

P(A ∩ B) = 67%

The probability is then calculated as:

P(B/A) = P(A∩B) / P(A)

The equation becomes

P(B/A) = 67% / 84%

Evaluate

P(B/A) = 79.8%

Hence, the probability that a bus chosen at random has a working radio given that is it ready for service is 79.8%
