A class of 30 music students includes 13 who play the​ piano, 15 who play the​ guitar, and 9 who play both the piano and the guitar. How many students in the class play neither​ instrument?

Respuesta :

I am not to sure but I think it’s 2 because you might not need to include the 9 students and 15 plus 13 equals 28 and you would have 2 left .

Answer: 2

Step-by-step explanation:

As given, out of 30 students, 15 play guitar and 13 play piano, thats 28.

Among these, 9 play both the guitar and the piano.

That means, only 2 remaining students play neither instrument. (30-15-13)
