O and are playing a game. The game has seven (7) rounds. They are initially located at "0" (marked as "x" in the graph below). For each round, they play rock-paper-scissors. If wins the game (which has probability), Awill make one step to the right, while remains at the location; if wins, or the game is draw (which has probability), O will make one step to the right, while A remains. After seven rounds, the winner is whichever who makes more steps. 0 1 2 3 4 5 6 7 (a) Let X, Y be the position (0 to 7) of and after seven rounds. What is the distribution of X, Y. Give the relevant parameters. (b) Compute the expected value of X, Y. (c) Find the probability that X ≤ 2. Express your answer up to 3rd decimal place.
