  • Story:

    At a barbershop music singing competition, choruses are judged on three scales: Music (quality of the arrangement, etc.), Performance, and Singing. The scales are supposed to be independent of each other, and each is scored by a different judge, but a friend claims that he can predict a chorus’s singing score from the other two scores. Are the scores really independent?
