Schicht werden 5000 Stück eines Typs A hergestellt. Bei der

Qualitätskontrolle werden 3% dieser

während einer Schicht zwischen $125$ und $180$ Teile aussortiert
|

werden.
|

\item Die aussortierten Teile werden nach Schichtende zur
|

Wiederverwertung in einem Kessel auf einmal eingeschmolzen. Wie

viele Teile muss der Kessel fassen, damit er mit einer

Wahrscheinlichkeit von min. $0{,}98$ nicht überfüllt ist?

$5000$ Teile pro Schicht hergestellt werden. Wie viele Teile

können maximal gefertigt werden, damit der Kessel mit einer
