12.1 | 1 | Die Wahrscheinlichkeit für das Ereignis E = "kein gelbes Fruchtgummi" lässt sich z. B. berechnen, in dem die Wahrscheinlichkeit des sog. Gegenereignisses ermittelt und diese schlussendlich von 1 subtrahiert wird: |

8.1 | 4 | \begin{aligned} |

10.1 | 5 | P(E) & = 1-(P(\text{"gelb, gelb"}) + P(\text{"gelb, rot"}) + P(\text{"gelb, weiß"}) + P(\text{"gelb, grün"}) ) \\ |

9.1 | 6 | & = 1- (313⋅212+2⋅313⋅712+2⋅313⋅212+2⋅313⋅112) \\ |
