The probability is something that most people think they understand, but it turns out to be more complicated than they imagined. There are only two possible results (we discount the chance that it will land on the edge) that is crown or piano.

The dice probability calculator that the next throw is heads is 1 in 2. Based only on that, if the next roll comes up as tails, then logically the next roll after which must heads - after all, it's a 1 in 2 chance, and that would be the second throw. But that's not how the dice probability works. Previous throws do not affect or determine later throws. If you get heads 20 times in a row, the chances of the next throw coming up tails are still 1 in 2, because there are only 2 possible outcomes, every single time.

So how does it work with dice? Provided we use standard 6-sided dice, rolling a single die gives a 1 in 6 chance that any number will come up, provided the die is perfectly manufactured and not weighted on one side. The chances of the same number coming up on a later roll are 1 in 6. It never changes.

But when you add another die in the mix, it becomes interesting. The possible results of throwing two dice are in the range of 2 to 12, so 11 results in all. You might think that the dice probability of getting a particular number is 1 in 11 - but you would be wrong. The total is now dependent on two factors, not one. If you roll a total of 2, you can only get one way - both dice must show a 1. If you roll 12, you can only get one way too-both dice must show a 6.

Simple so far, right? If you roll a 3, there are two ways to get it. Die A shows a 1, and Die B shows a 2 or Die A shows a 2 and die B shows a 1. The probability of rolling 3 is twice as likely as rolling a 2. As you progress through this math exercise, you will realize the easiest number to roll is 7. You can get this by scrolling 1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, or 6 + 1 - there are 6 combinations that give you 7 as a whole. We know this is a bit complicated, but we are working on a dice probability calculator, which will make calculations for you.

As you move away from 7, the combinations decrease. For 6 or 8, there are 5 combinations, for 5 or 9, there are 4 combinations, and so on. The total number of combinations corresponds to the number of faces on each matrix multiplied by each other - 36. This means that the probability of rolling 7 is 6 in 36, or 1 of 6. The dice probability of rolling 5 is 4 in 36, or 1 of 9. The probability of rolling 2 is 1 at 36. Adding a third die to the mix gives you a total of 216 possible outcomes, with at least a score of 3 or 18. Who said Dice's probability calculation was simple?
