Hi there!
[tex]\large\boxed{\text{ C. } 25\%}}[/tex]
We have the numbers:
0 1 2 3 4 5 6 7
There are 8 total numbers, and 2 of those numbers (1 and 3) represent a success. Therefore:
[tex]\text{p(success)} = \frac{\text{number of successes}}{total}\\\\\text{p(success)} = \frac{2}{8} = \frac{1}{4} = \boxed{25\%}[/tex]
