Sandy has a square, equilateral triangle, rhombus, and regular hexagon in her Shape Bucket, while Robert has a scalene triangle, kite, isosceles trapezoid, non-special quadrilateral, and obtuse isosceles triangle in his. Sandy will randomly select a shape from her Shape Bucket, while Robert will randomly select a shape from his.

Remember to justify your conclusions.

Who has a greater probability of selecting a quadrilateral? Justify your conclusion.

Sandy’s probability is

, while Robert’s is , which means that Robert has a greater probability. Who has a greater probability of selecting an equilateral shape? Justify your conclusion.

What is more likely to happen: Sandy selecting a shape with at least two sides that are parallel or Robert selecting a shape with at least two sides that are equal?
