Exploring Theoretical and Experimental Probability

What does theoretical probability represent?

• Probability of an event occurring under ideal conditions

• Probability based on past events

• Probability based on personal belief

• Probability of an event never occurring

How is experimental probability calculated?

• Number of times an event occurs divided by total number of trials

• Number of times an event does not occur divided by total number of trials

• Number of favorable outcomes divided by total possible outcomes

• Total number of trials divided by number of times an event occurs
