What is the difference between experimental probability and theoretical probability.

• Experimental is done in a lab.

• You have to think about theoretical probability.

• Theoretical probability is never correct and experimental is sometimes correct.

• One is mathematically calculated before an event. The other is calculated after an experiment or event happened.
