Question

Help me please somebody

Answer 1

Answer: 68%

Explanation:

From the table on the left-hand side, we observe that the total number of the surveyed seventh grade students is:

`12+7+13+6=38`

The number of seventh graders who do not play guitar is:

`7+13+6=26`

Hence, the probability that a randomly chosen seventh grader will play an instrument other than guitar is:

`(26)/(38)* 100\% = 68\%`
