I-Calculator ye-Permutation (nPr)

Bhala izilungiselelo ezilungisiwe zezinto r ezikhethiwe kusuka ku-n.

Izishintsho (nPr) —
Ifomula —

Iziphetho zivuselelwa uma ubhala.

Malunga nale khadi

you choose 10 items, you can choose 10 items, and 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. If r is larger than n, the calculator returns a dash.Per

Imibuzo ebuzwa kaningi

Yini ushintsho phakathi kwe-permutation ne-combination?

Kuhlelo lokushintshana, ukulandelana kubaluleke kakhulu (okuqala, owesibili, owesithathu yimiphumela ehlukene); kuhlanganise, akunjalo. Kuhlala kunezishintsho eziningi njengokuba kuhlanganise.

Yini ifomu lokushintshana?

nPr = n! / (n − r)!. Izingxenye ezingu-10 zithathwa njenge-3 ngasikhathi sinye: 10 × 9 × 8 = 720.

Ngabe kufanele ngisebenzise i-permutation?

Uma ukulandelana kubaluleke kakhulu: ukudweba abaqedela, ukugcwalisa indawo yokuqala/yesibili/yesibili, ukuphumula abantu emgqeni, noma ukwakha ikhodi elungisiwe.

Yini ezoba uma r ikhulu kuna-n?

Awukwazi ukuhlela izinto eziningi kunalokho okwenzekile, ngakho-ke imiphumela ayicacisiwe futhi ithuluzi libuyisela umgwaqo.

Yini i-nP0?

Kuyi-1 — kunendlela eyodwa kuphela yokuhlela okuthile, ukuhlela okungenalutho.

Yini i-nPn?

Ilingana ne n!, ngoba ukuhlela zonke izimo n ngokulandelana kuyinto efanayo ne factorial egcwele. Umzekelo 4P4 = 4! = 24.
