Permutazio kalkulagailua (nPr)
R elementuen ordena zenbatu n-tik aukeratutako r elementuen ordena.
Emaitzak idazten duzun heinean eguneratzen dira.
Kalkulagailu honi buruz
you choose 10 items, you can choose 10 items, and if r is greater than n, the tool returns a dash. If r is smaller than n, the calculator returns a dash. If r is larger than n, the calculator returns a dash. If r is smaller than n, the calculator returns a dash. If r is larger than n, the calculator returns a dash. If r is smaller than n, the calculator returns a dash. If r is larger than n, the calculator returns a dash.

Zer da permutazio eta konbinazio baten arteko aldea?
Permutazio batean ordenak garrantzi handia du (lehen, bigarren eta hirugarren emaitza desberdinak dira); konbinazio batean ordea ez. Beti dago gutxienez konbinazio kopuru bera duten permutazio kopurua.
Zein da permutazio-formula?
nPr = n! / (n − r)!. 10 elementu, 3 aldi berean hartuta: 10 × 9 × 8 = 720.
Noiz erabili behar dut permutazioa?
Ordena kontuan hartzen denean: amaitzaileak sailkatzea, lehen/bigarren/hirugarren postuak betetzea, jendea ilara batean eseritzea edo ordenatutako kode bat eraikitzea.
Zer gertatzen da r n baino handiagoa bada?
Ezin dituzu eduki dituzun elementu gehiago antolatzen, beraz, emaitza definitu gabea da eta tresnak marra bat itzultzen du.
Zer da nP0?
1 da, eta ez dago ezer antolatzeko modu bakarra, antolaketa hutsa.
Zer da NPN?
n! balio du, n elementu guztiak ordenan jartzea faktore oso bat bezalakoa delako. Adibidez, 4P4 = 4! = 24.
API — erabili kalkulagailu hau kodetik
Deitu kalkulagailu honi JSON amaierako puntu libre gisa — ez da gakorik behar. Bidali beheko eremuen balioak kontsultaren parametro edo JSON gisa. Anything you omit uses the same default this page is pre-filled with; an unknown parameter is a 400, never a silent zero. Irakurri APIaren dokumentazioa osorik →
