Web6 sep. 2024 · Given two numbers n and r, the task is to find the value of nPr. nPr represents n permutation r which is calculated as n!/(n-k)!. Permutation refers to the process of arranging all the members of a given set to form a sequence. The number of permutations on a set of n elements is given by n! where “!” represents factorial. nP r = n! / (n - r)! Web2 mrt. 2024 · Best answer Correct Answer - Option 1 : 5! Formula Used: nPr =n!/ (n-r)! nCr = n!/ [ (n-r)! r! ] n P r / n C r = r! Calculation: Given: n P r = 720 n C r = 6 n P r / n C r = r! … free move location
[Solved] If nPr = 720 and nCr = 120, then the value of r is:
WebCorrect option is B) nP r= (n−r)!n! =360 -- (1) nC r= (r!)(n−r)!n! =15 -- (2) Dividing eqn 1 by 2, we get. =>r!= 15360=24. =>r!=4×2×3×1=4! So, r=4. WebIf nP r=360 and nC r=15 then find the value of r A 5 B 4 C 3 D 2 Medium Solution Verified by Toppr Correct option is B) nP r= (n−r)!n! =360 -- (1) nC r= (r!)(n−r)!n! =15 -- (2) Dividing eqn 1 by 2, we get =>r!= 15360=24 =>r!=4×2×3×1=4! So, r=4 Was this answer helpful? 0 0 Similar questions If nC 12= nC 5, find the value of n. Medium View solution > WebIf nP r=720 and nC r=120, then what is the value of 'r'.
