1-41.

Sandy and Robert each have various polygons in their Polygon Buckets (see below). Sandy randomly selects a polygon from her Polygon Bucket, and Robert randomly selects a polygon from his.

 Sandy square equilateral triangle rhombus regular hexagon

 Robert scalene triangle kite isosceles trapezoid quadrilateral right isosceles triangle
1. ​Who has a greater probability of selecting a quadrilateral? Justify your conclusion.

$\text {Probability of an Event}=\large{\frac{\text{Number of outcomes of interest}}{\text{Total number of outcomes}}}$

$\text {P(Sally gets a quadrilateral)}=\large{\frac{2\text{ quadrilaterals}}{4\text{ polygons}}}=0.5$

2. Who has a greater probability of selecting an equilateral polygon? Justify your conclusion.

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