I got sick of working out how unlucky I have been in every game.
So I made a calculator to work it out for me!
http://gandalfgames.net/bloodbowl.phpI don't think it does it down to perfect accuracy - for example I tried out my season 1 game of pain vs notj where I rolled a stupid number of 1's - this calculator says 0.755% chance whereas according to what i posted on the forum it was 0.77%. This suggests my maths in the calculator is correct but that it's not rounding things properly. It's good enough to be used though.
It's really simple and basic, but does the job. Feedback appreciated. There is some basic validation built in, so try to break it if you want - if you end up with a blank screen or just a number then it has caught your dodgy input. If you get an error message then you have broken it so let me know.
The thing that may confuse you is that if you want to know, say, the chances of rolling 5 1's in 10 rolls, then what you *really* want to know isn't actually the chance of rolling 5 1's in 10 rolls, but actually the chance of rolling "at least 5 1's in 10 rolls" and that is what it works out.
