Random variable

  1. Jun 10, 2009 #1
    A random variable (RV) is a function that maps events in our probability space to real space. So it seems to me a random variable is a way to quantify(into real space) the physical events in our probability space? Is my understanding correct?

    Not really..first of all a RV can be either discrete of continuous (real).

    Secondly, you can just think of it as a variable that is in a simultaneous superposition of values with associated probabilities.
