Looking at the pattern so far, my opponent has played rock, scissors, paper, and scissors. They haven't shown a clear predictable pattern, but they've used scissors twice already. Given that I'm currently behind 0-2, I need to make a strategic choice. Rock would beat scissors, which my opponent has chosen most frequently (2 out of 4 rounds). Additionally, my opponent might anticipate me changing my strategy after losing with rock in round 3, making rock a less expected choice. Since there is no strong statistical pattern yet, I'm selecting rock as it has the potential to beat scissors if my opponent chooses to repeat that move.
