A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number cube was rolled, the number showing on the top face was recorded. The table shows the results.

Number Showing on Top Face Frequency
1 0
2 3
3 3
4 6
5 3
6 5

If you were to use these results to predict the probability of the next number showing on the top face, what type of probability would you be using?

Theoretical probability

Dependent probability

Independent probability

Experimental probability
