Six faces of chance
Sylvie D. Vauclair
Abstract
Suppose that you are playing a dice game with a friend. You throw two sixes and you feel very happy because you know that you are going to win. You even think that it may be unnecessary for your friend to throw the dice. The probability that he will also throw two sixes is very small indeed, and in any case you are sure that he cannot obtain a better score than yours. Now he throws the dice, and here comes a big surprise – a six is face up on one of the dice, while the second one splits in two, showing two faces: one face with a six and the other face with a one.
