Which statement below is true?

• The theoretical probability of rolling a 3 is greater than the experimental probability of rolling a 3

• The theoretical probability of rolling a 3 is less than the experimental probability of rolling a 3

• The theoretical probability of rolling a 3 is equal to the experimental probability of rolling a 3

• You cannot determine the theoretical probability.

Experimental Probability is:

• What will happen

• What actually happened

• What should happen

• What I think will happen
