When teaching Statistics, one of the hardest topics for student comprehension is probability. The Universidad Autonoma de Manizales is not the exception; this is why constantly people involved are developing different ways to get better results. From this comes the need for recognize how the student is doing in its learning process and establish mechanisms (new technology, games and others) when teaching statistics. This is how there was an intervention by the teacher about probability done in three different groups of students in engineer faculty during the second period of 2011. At first ideas and analysis were taken, so after that it was able to get some inputs for the design of new didactics units. In this new units, technology, didactics and ludic were adjusted into this aspects, so person in charge (teacher) were able to use them. On the groups were this aspects were used, they showed a better change and evolution in terms of probabilistic calculus and concepts. The amount of right questions answered increased and the arguments shown and explained by the students were elaborated better. At the same time activities done this way were taken in a good way by the students who highlighted the innovation of these new aspects.
