There are 7 sections, so the denominator of your probability fraction is simply 7. Examine each of the section numbers to see if the pointer landing on that section would count as a successful outcome. For example, 1: not even, not a multiple of 3, so not a success. Then 2... and so on. Count the number of sections that represent successful outcomes and that is the numerator of your fraction.
