The sample space for a number cube is {3, 6, 9, 12, 15, 18}.

The cube was rolled 78 times, and the 9 appeared 26 times. What was the experimental probability of rolling a 9?

1 answer

The experimental probability of rolling a 9 can be calculated by dividing the number of times the 9 appeared by the total number of rolls:

Experimental Probability = Number of times 9 appeared / Total number of rolls
Experimental Probability = 26/78
Experimental Probability = 0.3333 or 33.33%
