# The real brainteaser!

\(pi\) could also be said to be a random number producer, because the decimal equivalent is known to only 2000 million decimal places.

- i.e. Nobody knows the million millionth decimal place, each digit has the same chance to be the one.

So, if you had a transcendental number which consists of random digits, what would be the average difference two random digits side by side?

It should be \(\frac{0 + 9}{2}\) = 4.5

BUT IT ISN'T. What is it then?
