Government holds an auction to sell the right for oil exploration (and exploitation, if any found) on a tract of land to the highest bidder. Rules are: no reserve price; highest price wins and is paid; there will be a sale even if a single bidder shows up and bids zero.

All potential bidders have the same probability distribution for the net present value (NPV) of the oil accessible from the tract. Suppose it is a symmetric distribution with mean M. (Assume that a number of independent engineering studies have confirmed that the likelihood of NPV > M is equal to that of NPV < M.)

At least 30 potential bidders are expected to bid.

A day before the auction, a hot shot newspaper editor claims that "the winner will be a loser."

Discuss, prove or disprove.

Homework problem?

It can be. I intended it as a fun & games kind of problem.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
