understand the concepts of a discrete random variable and its associated probability function, and their use in modelling data

use relative frequencies obtained from data to obtain point estimates of probabilities associated with a discrete random variable

recognise uniform discrete random variables and use them to model random phenomena with equally likely outcomes

examine simple examples of non-uniform discrete random variables
