Mistoqsijiet li jsiru ta' spiss
X’inhi d-differenza bejn permutazjoni u kombinazzjoni?
F'permutazjoni l-ordni hija importanti (l-ewwel, it-tieni, it-tielet huma riżultati differenti); f'kombinazzjoni ma tkunx, dejjem ikun hemm mill-inqas daqs kemm hemm permutazzjonijiet.
X'inhi l-formula permutazjoni?
nPr = n! / (n − r)!. Għal 10 oġġetti meħuda 3 f’daqqa: 10 × 9 × 8 = 720.
Meta għandi nuża permutazzjoni?
Meta l-ordni hija importanti: il-klassifikazzjoni tal-finituri, il-mili tal-ewwel/it-tieni/it-tielet postijiet, il-post tan-nies fil-fila, jew il-bini ta' kodiċi ordnat.
X'jiġri jekk r huwa akbar minn n?
Inti ma tistax tirranġa oġġetti aktar minn għandek, sabiex ir-riżultat huwa mhux definit u l-għodda jirritorna dash.
X'inhu nP0?
Huwa 1 — hemm eżattament mod wieħed biex tirranġa xejn, l-arranġament vojta.
X’inhu nPn?
Huwa ugwali għal n!, għax l-arranġament ta' n-numri kollha f'ordni huwa l-istess bħal fatturjali sħiħ, pereżempju 4P4 = 4! = 24.
