Tomislav, MASON doesn't have a built-in probability distribution event 
scheduler.  It's a bit more low-level than that but if you think it'd be 
useful we should probably add something in.

If you want to hack your own, MASON lets you schedule events for any 
particular time in the future, so you could generate a random number, 
transformed to the appropriate distribution, and then schedule using 
that value as a time.

I'd be interested in adding this in but am presently out of the country, 
so it will have to wait for a week or two.
