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 n action be the states of the target at random. Let the set of tanks still in action be the states of the ystem. Show the transition probability matrix
