liest man:

Suppose you offer a friend a bet. You tell him that he can open at random any volume (such as the World Almanac) which contains tables of all sorts of numbers -the populations of the counties of the U.S., or the areas of seas, or the highest and lowest altitudes in each state, or the students enrolled in all the colleges and universities, or the motor vehicle deaths by states, or whatever.

From such a table you and he agree to pick out twenty numbers - the first twenty, or every other one until you have twenty - or according to any other scheme.

You say-

"Now you are my friend, and I want to treat you right. There are nine integers 1 through 9, and nine can't be divided evenly. So I will give you a generous proposition.

For every number that begins with 1, 2, 3, or 4, you pay me $1.

For every number that begins with 5, 6, 7, 8, or 9 I will pay you $1.

I pay on five numbers and you pay on only four, which just proves how generous I am."
