Trick or Treat Probability Project Your school needs your team to create a maze where each student pays $2 for the chance to get a trick or a treat. At the end of each path waits someone dressed in a costume to scare them or receive a bag of candy corn. Construct a maze for this event. From your maze construct a tree diagram and an area diagram and then answer the questions that follow. All work must be shown on your poster paper or power point. Your group will present the results. Be creative.
