Sorry :-)

It's perfectly understandable that numbers with as many as 10000 digits
with no particular a priori digit distribution property, will have some
"0" digits in them. But what is *very* interesting is a proof ;-)
Anybody playing some time with the problem will believe the property
is reasonnably true, that's another matter to find a rigorous justification.
