- Students use a hypothetical 1,000 two-way table to calculate probabilities of events.

Teacher Resources

Construct and interpret two-way frequency tables of data when two categories are associated with each object being classified. Use the two-way table as a sample space to decide if events are independent and to approximate conditional probabilities. For example, collect data from a random sample of students in your school on their favorite subject among math, science, and English. Estimate the probability that a randomly selected student from your school will favor science given that the student is in tenth grade. Do the same for other subjects and compare the results.

Students use a hypothetical 1,000 two-way table to calculate probabilities of events.

Students calculate conditional probabilities given a two-way data table or using a hypothetical 1,000 two-way table.
