Shapes with 13 to 20 sides are known as polygons. Specifically, a 13-sided polygon is called a tridecagon, a 14-sided polygon is called a tetrakaidecagon, a 15-sided polygon is called a pentadecagon, a 16-sided polygon is called a hexadecagon, a 17-sided polygon is called a heptadecagon, an 18-sided polygon is called an octadecagon, a 19-sided polygon is called an enneadecagon, and a 20-sided polygon is called an icosagon.
The largest possible sum with 2 six sided dice is 12.
The answer depends on what numbers are on the faces of the dice.
octahedron
A 20-sided shape is called a dodecahedron.
a set of multiple 6 sided dice, one or two 10 sided dice, an 8 sided dice, a 4 sided dice, a 12 sided dice, a 20 sided dice, the players handbook, the monsters manual, multiple people (at least 2 one of which must have the dungeon masters guide) and paper and pencil.
There are many different shapes and sizes of dice. The typical die that you find in most board games has 6 sides and 6 numbers. There are also 6-sided dice that are made with only 3 options though, and there are 20 and 30 sided dice out there as well. There are also 4 sided dice, 8 sided, 10 sided, and 12 sided that are quite common. They have other (even odd) numbered dice, and other types of dice with math symbols or pictures on them instead of numbers. Or letter dice for word games sometimes.
If the dice is 6 sided, the chances of rolling each number is about 17% (100/6) If the dice is 4 sided, the chances of rolling each number is 25% (100/4) Similarly, 8 sided = 12.5% 10 sided = 10% 12 sided ≈ 8% 20 sided = 5%
2 6-sided? 0% 2 10-sided? 7% 2 20-sided? 3.25%
A 20-sided polygon is called an icosagon.
rolling 8 on a 6 sided dice? in a single roll? approximately 0. on a 12 sided dice? one in 12. two six sided dice? 5/36
With 2 6-sided dice, 100% chance, since the maximum roll is 12.
0n a 6 sided dice. exactly 1. on two 6 sided dice, about 31/36
A die, many dice. So when you say a six-sided dice, do you mean six-sided dice, and if so, how many of them? Or, do you mean only one six-sided die? In that case, assuming the ide is fair, the answer is 1/6.
Regular 20 sided solid is an icosahedron, so a plane equivalent is presumably an icosagon?
The factors of 20 are 1, 2, 4, 5, 10, and 20. We can take 10 and 20 off the list, because they're not on the six-sided dice. So, 4 out of 6 sides of the dice will give us a factor of 20. That means we can expect (if the dice is fair) to get a factor of 20 about 4/6 of the time. 4/6 simplified is 2/3.
