Consumers in a certain state can choose between three long-distance telephone services: gtt, ncj, and dash. aggressive marketing by all three companies results in continual shift of customers among the three services. each year, gtt loses 30% of its customers to ncj and 15% to dash, ncj loses 10% of its customers to gtt and 5% to dash, and dash loses 30% of its customers to gtt and 30% to ncj. assuming that these percentages remain valid over a long period of time, what is each company's expected market share in the long run?
