To find the ratio of students to chaperones, we start with the given information: there are 2 chaperones for every 15 students.

We can express this as the ratio of students to chaperones:

\[
\text{Ratio of students to chaperones} = \frac{\text{Number of students}}{\text{Number of chaperones}} = \frac{15}{2}
\]

Thus, the correct ratio of students to chaperones is \(15:2\).

So, the answer is **15:2**.
