Probability: Theoretical vs. Experimental

What is 'Probability'?
Probability is the measure of how likely it is for an event to occur.
Probability can be written as either a fraction, decimal or percentage.

Types of Probability
There are two types of Probability - Theoretical and Experimental.
Theoretical Probability measures what we would expect to happen based on all of the possible outcomes and those we would like to have happen.
Experimental Probability is the measurement based on data from trials of an experiment, and the number of favorable outcomes during that time.
