Since the score is 1-4 in favor of the opponent, I need to win this round to have any chance of winning the game. Given the history of the game, the opponent has chosen rock, paper, and scissors multiple times, but has chosen paper twice in the last three rounds where there was a winner. To maximize my chances of winning, I should choose the option that beats the most frequently chosen option by the opponent in the last few rounds, which would be scissors to beat paper.
