Bu hasapçy hakda
you choose 10 items, then you can choose 10 items from the top r numbers. If r is greater 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. If r is smaller than n, the calculator returns a dash.

Köp soralýan soraglar
Permutasyon we birleşme arasynda näme tapawut bar?
Permutasyonda tertibi ähmiýetli (ilki, ikinji, üçünji dürli netijeler); birleşmelerde bu ähmiýetli däl. Her wagt birleşmelerden az-azdan birçok permutasyon bar.
Permutasyon formulası näme?
nPr = n! / (n − r)!. For 10 items taken 3 at a time: 10 × 9 × 8 = 720
Permutasyony näçe gezek ulanmak gerek?
Resimler örän möhüm bolsa: tamamlanyjylary sanamak, birinji/ikinji/üçünji ýerleri doldurmak, adamlary bir sahypada oturtmak ýa-da resimli kod gurmak.
Eger r n'den ulu bolsa näme bolar?
Sen özüňde bar zatlardan has köp zady tertibläp bilmeýäň, şonuň üçin netije belli däl we esbap bir çyzgyny gaýtarýar.
nP0 näme?
Bu 1 - hiç zat düzüp bilmek üçin diňe bir ýol bar, boş düzüw.
NPN näme?
Bu n! deňdir, sebäbi n elementleri tertibe salmak doly faktoraly bilen deňdir. Meselem 4P4 = 4! = 24.
