A 6-sided fair die is rolled 12 times. The results are listed below.

2, 4, 5, 4, 3, 6, 4, 3, 1, 5, 2, 4

Compare the theoretical and experimental probability of getting a 2.

• The theoretical probability is greater than the experimental

• The theoretical probability is less than the experimental

• The theoretical and experimental probabilities are the same

• Cannot be determined
