Question

In a group of 21 students, 8 students take Art courses, 7 students take Music courses. Two students take both courses. A student is chosen randomly from this group.

What is the probability that the student takes either Art or Music courses?

Answer 1

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
