<p>Heh. MS, i have a nice problem that arised when I was thinking about yours [I cannot concentrate on immunology because of this task! I think I will finally sit ad start to write it on paper. ;)]</p>
<p>My task is:</p>
<p>Find such an equation, that when it is raised to x-th power, it will give: (n over x), [I meant newton symbol].</p>
<p>OR </p>
<p>specifically to your task it will be:
((n over 1)(n over n-3)+(n over 2)(n over n-4) and so on)/(n!)^2</p>
<p>And now...
n over 1 [x1], n over 2 [x2], can be shown as: (1+S)^n , where S is the equation that raised to x will give (n over n-x-1)... and is dependant only on n.
[which will be probably n<em>coefficient</em>average... I cannot escape from this average!]</p>
