Axiom
Let $Z$ be a random variable.
Let $Z$ take the values $a_i$ with probability $p_i$, where $i \in \set {1, 2, \ldots, n}$.
Let $H_n: Z^n \to \R$ be a mapping which is to be defined as the uncertainty of $Z$.
${H_n}$ fulfils the following axiom:
- $H_n$ is a continuous function of its arguments.
