Question

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.

(Please help and if you can, show your answer so I can learn from it! Thanks in advance too!)

Answer 1

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

Answer 2

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
