Hi Folks, I'm working on a paper at the moment and need to use some kind of statistic but I'm not too great at stats. Here is the set up. 1) I have some volume. 2) Within this volume there is an even distribution of objects. 3) These objects 'explode' with a known frequency and their explosion sweeps out a known volume, which is much smaller than the total volume. I want to figure out how long it would take for explosions to have 'filled' the entire volume. I hope this question is clear. If you could give me some idea on how to start I would be grateful. Sorry if its not clear. PS - this is an astrophysics problem, not a weapons design problem!!!
