You can put this solution on YOUR website! A representative of the Environmental Protection Agency (EPA) wants to select samples
from 10 landfills. The director has 15 landfills from which she can collect samples.
the question is How many different samples are possible?
Note:: Selecting 10 from 15 is the same as not selecting 5 from 15.
------------
Ans 15C5 = 15!/(10!*5!) = (10*9*8*7*6)/(1*2*3*4*5) = 252
