[R] Advice regarding CVPR Rebuttal

Received reviews 5(3),3(4),2(3). Assume that- Case 1. None of the reviewers increase their score Case 2. One of the reviewers increases his score, giving 5(3),3(4),3(3).

In both the cases, what are my chances of getting an acceptance? I plan to withdraw and submit to another conference if the chances of acceptance appear slim
