Solution

To find the experimental probability of an event, you divide the number of times the event occurred by the total number of trials.

In this case, the event is rolling a sum of six, and it occurred 14 times. The total number of trials is 100 (because the students rolled the dice 100 times).

So, the experimental probability of rolling a sum of six is 14/100 = 0.14 or 14%.
