Video on Area Models in Probability Watch the video and answer the following questions on your own paper: 1) What are the events of the game? 2) Why did she FIRST divide the area model (the square) into 3 equal sections? 3) Why did she divide the top row of the area model into 3 equal sections? 4) Explain how she calculated the probability of getting a red marble from bucket #1 to be 1/9? 5) Explain how she calculated the probability of winning the game to be 23/36? https://www.sophia.org/tutorials/creating-area-models-and-finding- theoretical-proba

Post-Video Questions 6) Why is the following also an appropriate area model to represent this game? 7) What would the area model look like if you had draw a marble from bucket #1, replace it, then draw a second marble from bucket #1?
