Online dice probability calculator
ZicherCZ:
Now there's something I've been trying to find for quite some time - a calculator to which you can input a dice notation and the calculator will display the chance of the roll being higher or lower than a certain result.
For example, what's the chance of killing a demon with one BFG shot?
Now we know that a BFG is 10d6 damage, demon has 2 armor and 25 HP, so what's the probability of 10d6 >= 27?
I found the calculator here at anydice.com. I thought about sharing this with the rest of us here.
By the way, the probability of the example is over 94% :).

Um. By Law of Large Numbers, as the number of dice and sides go up (xdy), the distribution tends towards a normal distribution with μ = xE[dy] ~ x (1+y)/2, and σ² = Var[xdy], with an abuse of notation.
So your question can be recast into a "simple" look up on the normal distribution.
>.<
But the site is still cool. Heheheheh...

I have used Wolfram Alpha for calculating these probabilities. The site you used is better for that purpose though.

Also, you probably know that, but the BFG deals plasma damage, which means that you should calculate the probability for 10d6 >= 26, since the effect of armor is halved.

This could be VERY useful for determining how many levels of Brute to take before taking other skills in a Angel of Berzerk run

Thelaptop, that was a sample question. In fact, my motivation to find a site like this dates back to the time when WIKICOMP was still active. Plus, I was not asking for an average nor standard deviation ;).

Oops, you caught me here. Even as a sample question, it should have been a correct question.
