Incertesa i probabilitat : un passeig per algunes paradoxes i problemes clàssics de la teoria de la probabilitat Authors Josep Lluís Solé Abstract The humans always have feared the uncertainty that directs their lives. In this paper, we describe a kind walk along our behavior in front of randomness, from the old times, when it was divinized, until the present mathematical treatment with the Theory of Probability, that, as Laplace wrote, is only the common sense reduced to calculus.We will consider the first questions that appear in the correspondence among Pascal and Fermat, at the dawn of the Theory, and also some of the most classical problems, as for instance the martingale betting, and the random walk between barriers, selected in the so rich and enormous set of surprising results and paradoxes of this Theory.
