Random Variables

A random variable Z is a real valued function of the type Z: S → R on a sample space S. That means the function assigns a real number to every primitive event in the sample space. In other words, a random variable is a function mapping a sample space S to a set of real numbers R.

Question

Prove the proposition. For a successful or failed search in an ordered array with N keys, no more than lg N 1 comparisons are used.
