A '''die''' (plural: '''dice''') is a device for generating random numbers, traditionally between $1$ and $6$.
A '''die''' usually consists of a cube on which each face denotes a different number, usually (again) from $1$ to $6$.
Traditionally, opposite faces add to $7$, so:
:$1$ is opposite $6$
:$2$ is opposite $5$
:$3$ is opposite $4$.
The idea is that when you roll it, or throw it, or otherwise cause it to land upon a flattish surface, one of the sides will be face-up, and (with a good design of '''die''') which side that is can not be precisely predicted.
Hence it serves as a generator of a discrete uniform distribution.
By using '''dice''' with different shapes (usually either platonic solids or prisms), a different probability space can be generated.
