This category contains results about **Occurrences of Events**.

Definitions specific to this category can be found in Definitions/Occurrences of Events.

Let the probability space of an experiment $\EE$ be $\struct {\Omega, \Sigma, \Pr}$.

Let $A, B \in \Sigma$ be events, so that $A \subseteq \Omega$ and $B \subseteq \Omega$.

Let the outcome of the experiment be $\omega \in \Omega$.

Then the following real-world interpretations of the **occurrence** of events can be determined:

- If $\omega \in A$, then
**$A$ occurs**.

- If $\omega \notin A$, that is $\omega \in \Omega \setminus A$, then
**$A$ does not occur**.
