Try this:
	.EQ
	up 30 1 ~ left "/" ~
        { down 30 { sum from { n ^ = ^ 0} to N
        { left [ N! over { (N-n)!n! } right ] } } right "" sup 2
        .EN

Disclaimer: The 'left "/"' might be a something hacked into the version
of eqn I last looked at.  The code is so bad looking that it is
difficult to determine.  If it works, you have it.

The ~ move 1 em space while the ^ moves 1 en space.  So if more room is
needed, add more ~.  The  right ""  should solve the space problems with
the superscript.  This is not a bug since all superscripts are designed
to be (by default) 4 point sizes smaller than the text point size.  If
it doesn't work, add the size +2 again.

If this does not work, drop me an email note and we can arrange to talk
(I'm in NY).
