What is Theoretical Probability?

• The ratio of favorable outcomes to the total number of possible outcomes

• The ratio of favorable outcomes to the total number of trials in an experiment

• In probability, a controlled, repeated process (such as repeatedly tossing a coin).

• A single possible result.
