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. Based on these results, what is the experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face?
