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 both Art or Music courses?

13/21


8/21


2/7


5/7

Answer 1

i think it is 5/6 because you would have to choose a small amount

Answer 2

13/21

Explanation:

8/21 + 7/21 -2/21 = 13/21

You would do the minus two since two students take both.
