Abstract

The purpose of cultivating a probabilistic thinking involves a complex system of exercises and problems (to be solved or to be proposed to be solved). In general we are speaking about problems which refer to some "classic" random experiments about the tossing of a coin, the throwing of a dice, the randomly choosing of a point in a set of points, the extraction of a ball from an urn, etc. The modeling of such experiments is, we believe, a good support, but also an effective tool for creating a probabilistic thinking of pupils. In our work we present examples of modeling performed by using random number tables or by proposing programs in various programming languages. Keywords: probabilistic thinking, randomly choosing, modeling of random experiments, statistical definition of probability.
