Answer:

Step-by-step explanation:

First of all I'm going to presume it means an eight-grader chosen at random from the instrument players, if this is incorrect the question should have specified the total amount of students.

You have to add the amount of students of each of instrument to get the total:

5+9+10+9=33

then it says to not include the drum playing students so it goes from

[tex]\frac{33}{33}[/tex] to [tex]\frac{33-10}{33}[/tex] so its [tex]\frac{23}{33}[/tex] which we must now turn to a percentage.

so you divide the 23 by the 33:

23/33=0.6969....

then you multiply by 100 as it's a percentage:

0.6969...×100=69.6969...

and finally we round it do the nearest integer/whole number:

70 (we look at the tenths digit and it's a 6 so it's rounded up)
