you could call a random number routine (like jimmy mardell's prandom)
and have it select, say, values 0-9.  each one of these has ~
probability of 10%.  then map the numbers into different numbers such
as:

random num	map to		prob.
----------	------		-----
0 or 1		1		20%
2		2		10%
3,4,5		3		30%
6,7,8,9		4		40%

but as for an actual routine to do this, i would imagine you are on
your own :(.
