Refer to the following Chaos game to answer the question(s): Start with a square ABCD in which A is located at (0, 0), B is located at 
C is located at (27, 27), and D is located at (0, 27). Then, roll a fair die. We will say that A is the "winner" if we roll a 1, B is if we roll a 2, C is if we roll a 3, and D is if we roll a 4. If we roll a 5 or 6, we disregard the roll and roll again. Each roll of the die generates a point inside or on the boundary of the square according to the following rules.? Start: Roll the die. Mark the "winning" vertex and call it P1.? Step 1: Roll the die again. From P1 move two-thirds of the way straight toward the next winning vertex.
Mark this point and call it P2.? Steps 2, 3, etc.: Continue rolling the die, each time moving to a point two-thirds of the way from the last position to the winning vertex.Refer to the following figure to answer the question.
