Since the opponent has won 4 rounds and I have won 1 round, I need to win this round to have any chance of winning the game. Looking at the previous rounds, the opponent has chosen rock 4 times, paper 3 times, and scissors 2 times. The opponent has not chosen scissors in the last 2 rounds, so I will choose rock to beat scissors if the opponent chooses scissors. Additionally, since the opponent chose rock in the last round, they might choose a different option this round. Rock is a relatively safe choice and gives me a chance to win if the opponent chooses scissors.
