Article : Construction d’un solide à 5 faces - Colegiul National Emil Racovita (Cluj - Roumanie)

Résumé de la production: 
Is it possible to construct a solid, with 5 faces for example, such that the probability of getting each face is the same, 1=5 in the example with 5 faces. The problem's statement is equivalent to constructing a 5-sided fair dice. Such dice with 4 and 6 faces respectively already exist and are quite popular (for 4 faces there is the tetrahedron and for 6 faces the cube). In this article we will try to construct a 5-sided dice and from there an n-sided dice (n >= 4).
