+\shorttheorem[W. Punkt] Für Z.V $\cX$ und V.F $F_\cX$ gilt $\forall a \in \R$\\
+$\P[\cX = a] = F(a) - F(a-)$ mit $F(a-) := \underset{h\downarrow 0}{\lim} F(a - h)$.

+    \item $F$ in $a$ n. stetig, dann ``Sprunghöhe''\\ $F(a) - F(a-) = \P[\cX = a]$
+    \item $F$ stetig in $a$, dann $\P[\cX = a] = 0$
