A cube number is rolled 20 times and lands on 1 two times and on 5 four times. Find each experimental probability. Then compare
kykrilka [37]
The experiment probabilities are listed below:

One:  2 out of 20 = 2 / 20 = 0.1  or 10%

Four:  5 out of 20 =  5 / 20 = 1 / 4 = 0.25 = 25%

The theoretical probability of any single number is 1 out of 6 or about 17%.

The experimental probability for ones was less than and for fours it was greater than the theoretical probability.
