During their search for the reality stone on the planet Knowhere, all the members decide to divide and search individually for the stone. After traveling for some distance, Star-Lord suddenly spots three of his friends: Gamora, Drax and Rocket pointing their guns at each other. Matis explains to him that Thanos has obtained the stone and has changed the reality by disguising himself as one of them and the other two being his friends. Mantis says that the three of them decided for shooting truel (duel with 3 members). They will decide who goes first by lottery method and each person is to wait for their turn before firing at either of the other people. After the first round of shots fired, they will proceed in the same order until there is one person standing. Mantis further says that they know that Rocket is 100% accurate, Gamora is 80% accurate, and Drax is 50% accurate in his/her shooting. On each person’s turn, he can choose either of the two others to shoot or just skip his turn if required. Assuming that all three of them are intelligent and logical thinkers, Thanos would have chosen the best form as a disguise who has the highest chance of survival. Mantis hands Star-Lord a gun and asks him to kill Thanos. Can you help Star-Lord in deciding whom he has to target in order to kill Thanos?
