3-40.

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. Homework Help ✎

 Hint:Remember to justify your conclusions.
1. Who has a greater probability of selecting a quadrilateral? Justify your conclusion.

$\text{Sandy's probability is }\frac{2}{4}, \text{ while Robert's is }\frac{3}{5},\text{ which means that Robert has a greater probability.}$

1. Who has a greater probability of selecting an equilateral shape? Justify your conclusion.

1. 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?
