5. sam rolled a standard number cube 20 times. he rolled a five 6 times. what is the experimental probability of rolling a 5 based on sam’s experiment? give answer as a simplified fraction. ( and if you can, show your answer so i can learn from it! in advance too! )

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
3/10

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