Blue Cab operates 15% of the taxis in a certain city, andGreen Cab operates the other 85%. After a nighttime hitand-run accident involving a taxi, an eyewitness said thevehicle was blue. Suppose, though, that under nightvision conditions, only 80% of individuals can correctlydistinguish between a blue and a green vehicle. What isthe (posterior) probability that the taxi at fault was blue?In answering, be sure to indicate which probability rulesyou are using. [Hint: A tree diagram might help. Note:This is based on an actual incident.]
