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.
Experimental probability of landing on a 3 = number of times landing on a 3 / total number of rolls
Experimental probability of landing on a 3 = 10 / 30 = 1/3
Therefore, the experimental probability of landing on a 3 is 1/3.
