A discrete random variable is one that can only take on a finite or countably infinite number of values. In this case, the random variable is the number of insurance policies sold, which can only take on a finite number of values (0, 1, 2, 3,..., 80). Therefore, the random variable in this experiment is a discrete random variable.
