Probability
Probability is the chance that something will happen, or how likely it is that some event will happen.
Sometimes you can measure a probability with a number - "There is a 10% chance of rain" - or you can use words - "It is unlikely to rain tomorrow."
In general:
Probability of an event happening = Number of favourable outcomes/ Total number of outcomes

Experimental vs Theoretical Probability
Experimental Probability: The result of an experiment or simulation (what actually happens).
Theoretical Probability: What we expect to happen, based on probable outcomes.
Sample Size: How many trials we do.
The more trials we do, the closer our experimental probability gets to our theoretical probability.
