Answer:
Theoretical probability is the likeliness of an event based on all possible outcomes. Theoretically, a coin should land on heads 50 times, and tails 50 times, if you were to flip it 100 times.
Flipping it 60 times would mean theoretical probability would be it landing heads up 30 times, and tails up 30 times.
This actually happening is unlikely though, which is why we also have emperical probability.
