- Not any random sequence. First, you must assume that the digits are
- uniformly distributed on {0,1,2,3,4,5,6,7,8,9}, second you must assume
- some type of independence. Furthermore, the statement is still then
- only true with probability one. e.g. 0000000000... is a random
- sequence and certainly is not normal.
