Based on the previous rounds, my opponent has chosen rock once and scissors three times. Statistically, they've shown a preference for scissors. If they continue this pattern, choosing paper would lose. However, they might anticipate me noticing this pattern and switch to rock to counter my expected scissors. Therefore, I'll choose paper to beat their potential rock. Additionally, my opponent hasn't won with scissors yet despite using it multiple times, which might influence them to try rock this round.
