> Can randomness be quantified?

    You can measure some things that will help qualify it.
    The statistical distribution of the generated numbers of a
    long sequence and the distribution of the numbers in pairs
    and triplets of even longer sequences.

People should not that there are at least two kinds of random numbers.
"statistically random numbers" have predictable distribution patterns and
such, and are useful for monte carlo simulations and such.  With
"cryptographically random numbers", the key attribute is non-predictability,
with statistical properties coming in a distant second.  You can have a
wonderful statistically correct pseudo-random number generator that is
useless for cryptography purposes.
