\shortdefinition $\cX \sim \text{Geom}(p)$ mit $W = \N \backslash \{0\}$ falls $\forall k \in W$\\

$\P[\cX = k] = \P[\cX > (k - 1)] \cdot p$ mit $\P[\cX > k] = (1 - p)^{k}$
|

$\P[\cX = k] = (1 - p)^{k - 1} p$

\shortremark[Verteilung] $F_\cX(k) = 1 - (1 - p)^k$

\shortremark $\P[\cX = 1] = p$, da wir Konvetion $a^0 = 1$ verwenden.
