Okay, here we have this:
Considering the provided information, we are going to calculate the experimental probability of rolling a 5. So we obtain the following:
Since the experimental probability is equal to the ratio between favorable trials over the total number of trials, we obtain the following expression:
Experimental probability of rolling a 5=19/(13+16+15+17+19+20)
Experimental probability of rolling a 5=19/100
Experimental probability of rolling a 5=0.19 or 19%.
