MathFest 2011 Backgammon Quiz

In August 2011, over 1000 mathematicians gathered in Lexington, Kentucky for MathFest 2011,  the annual summer meeting of the Mathematical Association of America. MathFest 2011 featured “Backgammon Night,” a free social event offering backgammon group lessons, a backgammon quiz designed especially for top-level mathematicians, and a backgammon tournament to test their newly-acquired skills.

The quiz, which we are presenting here, poses ten problems, with some weighted more highly than others, so that a perfect score nets 13 points. Art Benjamin, math professor at the Harvey Mudd College in Claremont, California, and a member of the USBGF Board of Directors, constructed the quiz. Art, along with Jennifer Quinn, math professor at the University of Washington, Tacoma, gave a post-quiz lecture, explaining the answers.
