basicly this calculater tells you when you should expect something to happen.(not garanteed if % lower than 100) the way it calculates this is by the chance of not getting it this amount of times you've tried. the program uses an algorythym [ if first roll = %total = % old else: %total + ( % old * % total ) = next set of % total ]
