The experimental probability of an event is calculated using the formula:
\[
\text{Experimental Probability} = \frac{\text{Number of times the event occurs}}{\text{Total number of trials}}
\]
In this case, the event is rolling a 5. The number of times 5 appeared is 15, and the total number of rolls is 30. Therefore, the experimental probability of getting a 5 is:
\[
\text{Experimental Probability} = \frac{15}{30} = \frac{1}{2} = 0.5
\]
Thus, the correct answer is:
\(\frac{15}{30}\).
