The first is a football with a sensor “sensor football” to determine when it crosses the goal line. The NFL and college football teams would use it to help alleviate time-consuming video reviews during goal-line situations. The second is a football “stats football” that tells you the speed, length, and spin rate of throws. The “sensor ball” for the NFL and college requires complicated technology. In addition, it needs an agreement with stadiums to put underground sensor strips on the goal line. Internal analysts predict a 50% success rate, 10 million dollars to develop, but with the potential to generate 100 million dollars in revenue. The “stats ball” has a 90% success rate, and 5 million dollars to develop, with the potential to generate 75 million dollars in revenue. At what percentage success rate would the “sensor ball” lead to the higher expected value compared to the stats ball?Find particular solution

- Give clear explanation!!PLEASE EXPLAIN ALL THE STEPS FOR SOLVING THIS PROBLEM:Market share. Consumers can choose between three long-distance telephone services: GTT, NCJ, and Dash. Aggressive marketing by all three companies results in a continual shift of customers among the three services. Each year, GTT loses 5% of its customers to NCJ and 20% to Dash; NCJ loses 15% of its customers to GTT and 10% to Dash, and Dash loses 5% of its customers to GTT and 10% 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?Fast plz hand written otherwise skip.....i'll rate plzzzzz asap....
