 \subsection{Bedingte Wahrscheinlichkeit}
 \shortdefinition Für $(\Omega, \cF, \P)$ mit $A, B \in \cP(\Omega)$ mit $\P[B] > 0$:
 \[
-    \P[A | B] = \frac{\P[A \cap B]}{\P[B]}
+    \P[A | B] = \frac{\P[A \cap B]}{\P[B]} \quad (= \P[A] \text{ wenn $B$ eingetreten ist})
 \]
 \shortremark $\P[B | B] = 1$
