The experimental probability of an event is calculated by taking the number of successful outcomes divided by the total number of trials.
In this case, Deon rolled a six-sided die 40 times and the number 4 appeared 15 times. Therefore, the experimental probability \( P \) of rolling a 4 is:
\[
P(4) = \frac{\text{Number of times 4 appears}}{\text{Total trials}} = \frac{15}{40}
\]
Calculating this:
\[
P(4) = \frac{15}{40} = 0.375
\]
Thus, the experimental probability of rolling a 4 in the next trial is **0.375**.
