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 in the simplest form of a fraction

The experimental probability of landing on a 3 when a six-sided number cube is rolled 30 times is given by:

Experimental probability = number of times landing on 3 / total number of rolls
Experimental probability = 10 / 30 = 1/3

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