Keďže si Dano pamätal tri znaky zo štyroch, musíme zistiť počet možných rozšírení pre posledný znak hesla.
Dano si pamätá, že posledný znak je buď 3, 5, 7 alebo 9. Každá z týchto možností nám dáva jedno možné rozšírenie hesla. Preto existujú 4 možné rozšírenia pre poslednú postavu.
Odpoveď: Existujú 4 možné rozšírenia pre Danovo heslo.
