Definition of a random variable

Hi guys
Definition from book: A random variable $X$ is defined to be a numerically valued function of the elementary events $Ei$

what does it mean it plain english? I understand the numerical and the random aspect but how is it a function of events?

Above gives a much more extensive discussion. It is not easy to answer your question in a short summary, particularly since the book definition is incomplete.
Thanks from 123qwerty and dthiaw
