Theoretical probability is calculated based on reasoning or mathematical principles—it's what we expect to happen. When outcomes are equally likely, the probability of an event is given by
where n(A) is the number of outcomes in event A, and n(U) is the total number of outcomes in the sample space.
For example, when rolling a six sided die, n(U)=6 is the number of possible die rolls. If we define A to be the event "an even number is rolled", then n(A)=3. Thus
