Overall, this quiz went rather poorly.  Students needed more practice with two-way tables, Venn Diagrams, conditional probability, and testing independence.  This is why we decided for an extra day of practice (Day 52) for next year.

​

In the Venn Diagram, students did well identifying the value that goes in the center (overlap), but often put incorrect values for the left and right Pacmans.  Students also struggled with conditional probabilities.
