<h3>d.</h3>
The total number of students is 166. Of those, the number who neither surf nor skateboard is 24. That percentage is ...
24/166 × 100% ≈ 14.5% . . . . students who don't surf or skateboard
_____
<em>Additional comment</em>

This sort of table is called a "two-way table." One set of categories is represented in rows, another set is represented in columns. This table is filled with <em>frequencies</em>. Such tables can also display <em>relative frequencies</em> by dividing the entire table by the total of totals in the lower right corner.

The range is the difference between the largest number and the smallest number. This means you subtract the smallest number from the largest number. If the range is 8, then you can add 8 to the smallest number on the list to get the largest number, m.
Our smallest number is 12, so add 8 to 12.
8 + 12 = 20, so m is 20.
