None! They're equivalent.

What is the difference between experimental and theoretical probability?
Simply put, theoretical probability is what we expect to happen with the data we have. While experimental probability is what actually occurs when we try the experiment.

What is an independent and dependent event?
An independent event is an event in which the outcome isn't affected by another event. A dependent event is affected by the outcome of the first event/the experiments before.
