	Hello,

	I am looking for information concerning the nameing of a certain
paradox. It is called the Petersberg Paradox. Can anyone tell me why it
is called the Petersberg Paradox?

	The Petersberg Paradox goes something like this:

	The probability distribution of X is given by f(x) = (1/2)^x for
x = 1, 2, 3, ..., infinity. The expectation E(2^x) does not exist.

	in other words a players expectation is infinite if he/she is to
receive 2^x dollars when in a series of flips of a balanced coin, the
first head appears on the xth toss.

	If available sources would be appreciated.

Thanks,
Brian D. Carlson
