What is the result of the verbal poll and why do you think no one objected to an open ballot this time on act 3

The vote is 11 to 1, and 3rd Juror stands alone. At first, he stands firm, saying that he will be the holdout to make this a hung jury. He launches himself into a final massive rant against the boy that descends into nonsense. 8th and 4th Jurors make a short final plea, and 3rd Juror finally concedes, saying “All right. Not guilty.” The Foreman informs the Guard that they have reached a verdict, and the Jurors leave the courtroom. No one objected to the open ballot because the 3rd Juror was the only vote needed to make the poll unanimous.
