Author:Interactive Mathematics Miscellany and Puzzles, Alexander Bogomolny
Description: With the eerie but uniform distribution of digits of randomly selected numbers, if the numbers under investigation are not entirely random but somehow socially or naturally related, the distribution of the first digit is not uniform. One may expect 1 to be the first digit of a random number in about 30% of cases, 2 will come up in about 18% of cases, 3 in 12%, 4 in 9%, 5 in 8%, etc. This is known as Benford's Law.
