nCr=n!/(r!(n-r)!)
nCr = nPr/r!
The coefficient of x^r in the binomial expansion of (ax + b)^n isnCr * a^r * b^(n-r)where nCr = n!/[r!*(n-r)!]
nCr=n!/r!/(n-r)!
On some calculators there is an "NCR" button. Pressing the amount of total objects (in this case people), pressing "NCR", then pressing the amount of objects to be randomly taken would give us the total amount of combinations. In this case, 10 NCR 5= 252.........this isnt the right answer it is 28
nCr + nCr-1 = n!/[r!(n-r)!] + n!/[(r-1)!(n-r+1)!] = n!/[(r-1)!(n-r)!]*{1/r + 1/n-r+1} = n!/[(r-1)!(n-r)!]*{[(n-r+1) + r]/[r*(n-r+1)]} = n!/[(r-1)!(n-r)!]*{(n+1)/r*(n-r+1)]} = (n+1)!/[r!(n+1-r)!] = n+1Cr
nCr = nPr/r!
This is a combination problem; use the nCr formula. nCr = 15! / ((15-4)!*4!) nCr = 15! /(11!*4!) nCr = 1365
The NCR's overall leader is President Aaron Kimball. The military effort against the Legion, is General Lee Oliver.
Press MATH and select PRB at the top. The third option, nCr, is combination. Example: To find C(10,4) type: 10 nCr 4
