Throw two dice at a time, and the number of points will have several different results.

Dice has six sides. Theoretically, every time you throw two faces, there are 6*6=36 kinds, namely11[12] [13] [14] [15] [/kloc].

2 1 2 2 [2 3] [2 4] [2 5] [2 6]

3 1 3 2 3 3 [3 4] [3 5] [3 6]

4 1 4 2 4 3 4 4 [4 5] [4 6]

5 1 5 2 5 3 5 4 5 5 [5 6]

6 1 6 2 6 3 6 4 6 5 6 6

But because the two dice are the same, it can be seen from the combination of the above figure that there are actually only 2 1 different results.
