After polling a class of 20 music students by a show of hands, you find that 8 students play the guitar and 9 students play the piano. Given that information, what is the minimum number of students in this music class who play both the guitar and the piano?

F. 0
G. 1
H. 8
J. 9
K. 17

I don't get how it's 0 Ms. Sue. Would we do 9 + 8 = 17, then do 20 - 17 = 3?

Oh wait, sorry. 3 is not even an answer choice.

The least number that plays both intruments is 0.

To find the minimum number of students who play both the guitar and the piano, we need to determine the overlap between the two groups.

We know that 8 students play the guitar and 9 students play the piano. However, we don't know the exact number of students who play both instruments.

To figure out the minimum number of students who play both, we need to consider the maximum possible number of students who play each instrument individually and then find the lowest value.

The maximum number of students who play the guitar individually is 8 (as given), and the maximum number of students who play the piano individually is 9 (as given).

If all 8 students who play the guitar also play the piano, then the minimum number of students who play both is 8.

Therefore, the correct answer is option H. 8.
