Examples, solutions, videos, and lessons to help High School students learn how to 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.

- Model real-life data using two-way frequency tables.
- Recognize that the conditional probability, p(A|B), represents the joint probability for A and B divided by the marginal probability of B.
- Use p(A|B) = p(A ∩ B)/p(B) to calculate conditional probabilities from a two-way frequency table.
- Apply the definition of independence to a variety of chance events as represented by a two-way frequency table.
