The probability of choosing a student who takes either Art or Music courses is 15/21. To find this, we add the number of students who take Art (8) to the number of students who take Music (7) and subtract the number of students who take both courses (2) to account for the overlap. So, 8 + 7 - 2 = 13. And, the probability is 13/21
