ስለዚህ መተግበሪያ

the first 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 smaller than n, the calculator returns a dash. If r is smaller than n, the calculator returns a dash.PermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermutationsPermu

የሚጠየቁ ጥያቄዎች

በአንድ ማስተካከያና በአንድ ማቀናጀት መካከል ያለው ልዩነት ምንድነው?

በአንድ መተካት ሒደት ውስጥ ሒደት አስፈላጊ ነው (መጀመሪያ፣ ሁለተኛ፣ ሦስተኛ የተለያዩ ውጤቶች ናቸው)፤ በአንድ ማቀናጀት ውስጥ አይደለም። ሁልጊዜ እንደ ማቀናጀት ብዙ መተካቶች አሉ

የፕሬምዩቴሽን ፎርሙላ ምንድን ነው?

nPr = n! / (n − r)!. ለ 10 ነገሮች 3 ጊዜ መውሰድ: 10 × 9 × 8 = 720.

መተካት ለምን ያስፈልጋል?

ትዕዛዙ አስፈላጊ ከሆነ: የመጨረሻውን ተሳታፊዎች ደረጃ መስጠት፣ የመጀመሪያ/ሁለተኛ/ሦስተኛ ቦታዎችን መሙላት፣ ሰዎችን በመስመር ላይ መቀመጥ፣ ወይም የተዘጋጀ ኮድ መፍጠር.

r ከ n የበለጠ ከሆነ ምን ይመጣል?

ከሌለህበት በላይ ነገሮችን ማደራጀት አትችልም፣ ስለዚህ ውጤቱ ያልተገለጸ ነውና መሳሪያው ድንጋይ ይመለሳል

nP0 ምንድን ነው?

1 ነው - ምንም ነገር ለማስቀመጥ አንድ መንገድ ብቻ አለ፣ የባዶው መቀመጫ።

nPn ምንድን ነው?

ይህ n! ጋር እኩል ነው, ምክንያቱም ሁሉንም n ነገሮችን በዝርዝር ማዘጋጀት እንደ ሙሉ ፋክቶሪያል እኩል ነው. ለምሳሌ 4P4 = 4! = 24
