The jury may take exhibits and other papers received in evidence. If the judge allows the jurors to take notes during the trial, the judge may also allow those notes to be used in deliberations. A jury may communicate with the judge during deliberation. However, any communications from the judge to a deliberating jury must be received in court with both counsels present. A jury may not conduct its own investigation. Members of the jury may not fraternize with counsel or the judge during trial or deliberation. Each juror must make up his own mind. Each juror must share in the decision reached. A jury may not decide a verdict by any elements of chance. The jury may not make a decision based on an average of the decisions of each of the jurors. However, an average may be used to assist in making a final decision so long as the jurors were not bound to the average in advance.
