We present the mathematical theory of the Russian roulette. The theory of Russian roulette has many interesting properties.
Let F[p,n,m,v] be the probability of the v-th man losing in the Russian roulette game with p-players, n-chambers and m-bullets. If we make a triangle with F[p,n,m,v], then we get a triangle of fractions where its denominator and numerator form a pascal's triangle-like pattern.
The expectation of the player’s death has very interesting properties. For example the expectation is log(2) in a Russian roulette game with 2 players.
This article includes many new mathematical theorems, but many high school students can understand them. Many of the ideas in this are presented by high school students.
