6. Three tanks A, B AND C fight a duel. Tank a hits its target with probability 2/5, tank B with probability 2/3, and tank C with probability 3/5. Shots are fired simultaneously and once a tank is hit it is out of action. When all three tanks are in action, each one picks its target at random, Let the set of tanks still in action be the states of the target at random. Let the set of tanks still in action be the states of the system. Show the transition probability matrix.
