Experimental probability is the ratio of number of times the event is occurring to the total number of the trials of the experiment. This implies that it is a ratio of the number of times an event is occurring to the total number of times that the activity has been repeated. Thus we shall use the formula:
Experimental probability=(# of occurrence of the event)/(total # of trials made)
=6/20
=3/10
Answer: 3/10

Experimental probability = Number of rolls for a number/Total number of rolls = 6/20 = 3/10
