Abstract: 

In this research we approach a fundamental stochastic idea. The random variable is based on other mathematics and probabilistic concepts and, in turn, is the support of many probability and statistics subjects. In this paper, we present some results from an exploratory study carried out with two university students. The aim was observing the difficulties the students face when they try to solve a problem that involves the concept of random variable.
