Subject: Re: Differences in permutations and combinations


The way to differentiate between permutations and combinations is by
saying that if you can physically differntiate between objects then
you use Perumations else use Combniations

for exampe if you are rearranging people in a row, then you use
permutations

And if you are arranging balls, blue, red, etc... then you do not
differentiate between individual balls (as they are alike) so you use
combinations
