            Exemplu de utilizare a tabelului:

            Gasiti probabilitatea de aparitie a exact doua prune pe o linie de castig a unui aparat de sloturi cu 3 role, avand 64 stopuri si 7 prune pe fiecare rola.

            Urmarim intersectia liniei t = 64 cu coloana c = 7 si gasim probabilitatea P = 0.03196335= 3.196335%.
