Of Dice and Men When billionaires play dice: Business magnate Warren Buffett once attempted to win a game of dice with Bill Gates using Efron's dice. "Buffett suggested that each of them choose one of the dice, then discard the other two. They would bet on who would roll the highest number most often. Buffett offered to let Gates pick his die first. This suggestion instantly aroused Gates's curiosity. He asked to examine the dice, after which he demanded that Buffett choose first." Bill Gates speaks: insight from the world's greatest entrepreneur by Bill Gates and Janet Lowe Efron's dice are a set of 4 6-sided dice labelled as follow: die A: 4, die B: 3, die C: 6, die D: 5, 4, 3, 6, 5, 4, 3, 2, 5, 4, 3, 2, 1, 0, 3, 2, 1, 0 3 2 1 Here are the rules for a two-player game: - each player chooses one die from the set - they both roll their die - the player with the highest score wins.

Warren Buffett© Bloomberg/Getty Images In June 2006, he announced a plan to give away his fortune to charity, with 83% of it going to the Bill & Melinda Gates Foundation. In a letter to Fortune Magazine's website in 2010 Buffett remarked: My luck was accentuated by my living in a market system that sometimes produces distorted results, though overall it serves our country well... I've worked in an economy that rewards someone who saves the lives of others on a battlefield with a medal, rewards a great teacher with thank you notes from parents, but rewards those who can detect the mispricing of securities with sums reaching into the billions.
