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, which is the minimum number of students in this music class who play both the guitar and the piano?.



Answer :

There must be zero students in this music class who are proficient on both the guitar and the piano.

Eight pupils play the guitar and nine kids play the piano, according to a show of hands poll of the 20 students in the music class.

You must consider the range for which the guitar and piano players may overlap in order to determine the minimal number of pupils in a class of 20 who can play both the guitar and the piano when 8 can play the guitar and 9 can play the piano. For instance, the greatest number of musicians who can both play guitar and piano is eight.

The least overlap they can have would be the minimal. As the sum in this case is 20, the two groups may not be connected since 9 + 8 or 17 is less than 20. Therefore, 0 is the minimum.
