A fair die is rolled. What is the probability of rolling a number greater than 4?

A bag contains 5 green, 3 blue, and 2 red marbles. If a marble is drawn at random, what is the probability that it is not blue?

8. A die was rolled 40 times. The results of each roll are given in the table below. If the die is rolled

once more, find the experimental probability for each result.

P(1), P(2), P(3), P(4), P(5), P(6)

A die was rolled 40 times. The results of each roll are given in the table below. If the die is rolled once more, find the theoretical probability for each result.
