Theoretical probability- what the probability "should be" if all outcomes are equally likely.
... then all outcomes are equally likely. Nothing more, nothing less. You can always re-define the outcomes so that they are not all equally likely. For example, on a single roll of a fair die, the numbers 1 to 6 are equally likely. But redefine the events so that Event A = prime number Event B = composite number Event C = neither prime nor composite number then P(A) = 1/2, P(B) = 1/3 and P(C) = 1/6 : events with unequal likelihood.
It is the set of all possible outcomes of the experiment.
All possible outcomes of an experiment is known as a sample space. This will include an exhaustive list of all the possible results to be achieved.

Theoretical probability- what the probability "should be" if all outcomes are equally likely.
Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.

Is the number of all possible outcomes of an experiment. The number depends on the experiment.
If the outcomes of a trial or experiment are all equally likely then the probability ratio for a specific event is the ratio of the number of outcomes that are favourable to the event divided by the total number of possible outcomes.
