For the throw of a single die, all outcomes are equally probable. But in the throw of two dice, the different possibilities for the total of the two dice are not equally.
AnyDice is an advanced dice probability calculator, available online. It is created with roleplaying games in mind.
Since TFT uses dice exclusively (as does GURPS), these tables do not include any other possibilities. The first table gives the probability of rolling a specific number; the second table gives the probability of rolling . All rights reserved.

### All dice possibilities - phone numbers

But the real world, or even a simulated real world, never matches completely with calculated probability. The first is doing it directly. What if the dice aren't fair, or aren't independent of each other? You can change the numbers and the condition to see what happens. Like the first condition, there are two ways to work this out. For example, if you throw three dice, what is the chance of one of the dice getting less than five?
