      <subfield code="a">Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. Quins científics van interessar-se per la probabilitat en els seus inicis?, quins altres van fer-la evolucionar? i quins conceptes coneixem i apliquem a l'actualitat? són preguntes que el treball teòric es proposa respondre.&#xd;
Pel que fa a la part pràctica del treball, el seu objectiu és el de crear un mecanisme capaç de generar nombres aleatoris a partir d'un taulell condicionat per paràmetres.&#xd;
El treball s'estructura en 4 blocs que aborden diversos camps de la probabilitat: la història de la probabilitat, els conceptes bàsics de la probabilitat, una introducció pràctica al mecanisme aleatori i el treball de camp. Els resultats finals rebel·len la possibilitat de generar nombres aleatoris a partir d'aparells senzills.</subfield>

      <subfield code="a">Research project carried out by a pupil of secondary education and rewarded with a Prize CIRIT to foster the scientific spirit of the Youth in year 2009. Which scientists were interested in Probability in the beginning? Which other scientists made the theory evolve? And which concepts do we apply nowadays?&#xd;
These are some of the questions that this research paper intends to answer:&#xd;
To prove this theory, it is created a mechanism which is able to generate random numbers from a board conditioned by parameters.&#xd;
This paper is structured in 4 different sections that explain different fields of Probability: its history, its basic concepts, a practical introduction to a random mechanism, and a field work. The final results of this final part reveal the possibility of generating numbers almost randomly from very simple devices.</subfield>
