A taxicab was involved in a fatal hit-and-run accident at night. Two cab companies, the Green and the Blue, operate in the city.You are told that:

• 85% of the cabs in the city are Green and 15% are Blue.

• A witness identified the cab as Blue.

The court tested the reliability of the witness under the same circumstances that existed on the night of the accident and concluded that the witness was correct in identifying the color of the cab 80% of the time.What is the probability that the cab involved in the incident was Blue rather than Green?
