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 the 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?

• 2/5

• 3/20

• 1/3

• 3/5

A number cube has 6 sides labeled 1 to 6. When the number cube is rolled, the theoretical probability of it landing on a number greater than 2 is ⅔.

What is the probability of the number cube NOT landing on a number greater than 2?

• 5/6 , because the probability of the number cub landing on a number greater than 2 is 1/6

• 1.      2/3 , because the probability of the number cub landing on a number greater than 2 is 1/3

• 1/3 , because the probability of the number cub landing on a number greater than 2 is 2/3

• 1/6  , because the probability of the number cub landing on a number greater than 2 is 5/6
