In this paper we present a short introduction and survey of the calculus often called "Quantum Logic", and we point out the difficulties which prevent us from considering this calculus as a logic. It is furthermore shown that the probability calculus for a quantal system is a generalization of the classical probability calculus, which gives a more general meaning to the notion of random variable.
