Definition of equal distributions

The probability distribution of Pr:\ohm\to[0,1] is called equal if: \forall w \in \ohm : Pr(w) = \frac{1}{n}

Laplace-Formula

If the probability of each outcome is evenly distributed, then it's possible to calculate the chance of an event using Laplace-Theorem.

With A \in \ohm and Pr: \ohm \to [0,1] being a equal distribution, then the following holds.

Pr(A) = \frac{|A|}{|\ohm|}
