How Many Jurors Must Agree in a Slip and Fall Accident Case?

I am involved in a slip and fall accident  case in Tennessee state court .  How many jurors must agree to a given result?

Unless the parties to the lawsuit agree otherwise, twelve jurors will decide the case and all twelve must find in favor of the plaintiff (the person bringing the lawsuit) or the defendant (the person or entity that has been sued.)  If less than twelve people agree on the outcome, the judge will declare a mistrial and the case will have to be tried again.
