What does theoretical probability depend on?

• None of the above

• Actual outcomes

• Past events

• Predicted outcomes

How is experimental probability calculated?

• Number of desired outcomes over total outcomes

• Number of trials over number of successes

• Number of outcomes over number of events

• Number of successes over number of trials

What distinguishes experimental probability from theoretical probability?

• Theoretical is based on actual outcomes

• Experimental is based on predictions

• Experimental is based on actual outcomes

• Theoretical is always more accurate
