What does theoretical probability depend on?

• Actual outcomes of an experiment

• Past events

• None of the above

• Predicted outcomes before an experiment

What is the difference between theoretical and experimental probability?

• Experimental can only be calculated with a computer

• Theoretical is based on predictions, while experimental is based on actual experiments

• Theoretical is based on actual outcomes, while experimental is not

• There is no difference

How is experimental probability calculated?

• Number of trials over number of successes

• Number of desired outcomes over total outcomes

• Predicted outcomes over actual outcomes

• Number of successes over number of trials

If a dice is rolled 60 times and number 5 comes up 8 times, what is the experimental probability of rolling a 5?

• 1/5

• 1/7

• 1/8

• 1/12
