# Random variables
A variable: a thing that can take on a bunch of different values.
Which part is random?
* Formally, a random variable *deterministically* maps elements of one set to another.
* Once we have the value in the first set, i.e. the "measurement" of "what kind of a Monday it is," we know the value in the second, i.e. the color of shirt I will wear.
* It is these measurements that are random, as these can only be so precise.
