Australian families in the year 2300 live in one of three regions: urban (U), suburban (S), and rural (R). We assume that the probabilities of the movements between these regions per decade are fixed and are as follows:Urban Families: The probability of an urban family moving to rural regions is 0.1. The probability of moving to suburban regions is 0.1. Hence, the probability of staying where they are is 0.8.Suburban Families: The probability of a suburban family moving to rural regions is 0.4.
