A six-sided number cube is rolled 30 times and lands on 3 ten times and on 5 eight times. Calculate the experimental probability of landing on a 3. Write your answer is the simplest form of a fraction...

Experimental probability = Number of times event occurs / Total number of trials

Number of times landing on a 3 = 10
Total number of trials = 30

Experimental probability of landing on a 3 = 10/30 = 1/3

Therefore, the experimental probability of landing on a 3 is 1/3.
