Question 345770: I'm trying to figure out how this answer was derived from this problem. I understand how to do the Permutation problems but not the combinatorics
C (17, 4) the answer given was 35. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! I understand how to do the Permutation problems but not the combinatorics
C(17, 4) the answer given was 35.
--------------------------------------
Formula: C(n,r) = n!/(n-r)!r!
--------
C(17,4) = 17!/[13!*4!] = (17*16*16*14)/(1*2*3*4) = 2380
---------------
The answer is definately not 35.
