 \shortdefinition[Sigma-Algebra] $\cF \subseteq \cP(\Omega)$ ist $\sigma$-Algebra, falls:
 \begin{enumerate}[label=\textbf{E\arabic*.}]
-    \item $\Omega \subseteq \cF$
+    \item $\Omega \in \cF$
     \item $A \in \cF \Rightarrow A^C \in \cF$ ($A$ Ereignis $\Rightarrow$ nicht $A$ auch)
     \item $A_1, A_2, \ldots \in \cF \Rightarrow \bigcup_{i = 1}^\infty A_i \in \cF$\\
