Did you know that when you roll two dice at once and add them together, some results are more common than others? By itself, one die has an equal probability of giving each result, 1 through 6. The die can only land on one side at a time, of course.

But when you have two dice, there are multiple ways that the dice can give you the same total results. For example, if you have a total result of 8, the dice might both show a result of 4. Or one might be a 3 and the other is a 5. Or one is a 2 and the other is a 6. There are many ways for this to happen!

On the other hand, if you have a total result of 2, that means both dice have a result of 1. There is no other way to get a total result of 2. The same is true when you get a result of 12. Both dice have to show a result of 6 for this to happen. There is no other way.

The chart below shows you the probability of rolling each result (rounded to the nearest whole percent). Try using this knowledge to your advantage the next time you have to guess the result of rolling two dice!
