Instructional Ideas

  • Include the second video on two-way tables by Mr. Ladak
  • Lead a discussion on joint, marginal, and conditional relative frequencies
Classroom Considerations

  • The class should be familiar with calculating simple probabilities

  • The answer key shows the completed two-way tables used to determine the solution
  • Requires the class to complete tables and to construct them from scratch

  • The solution for #10 is missing from the answer key
