Drills
A cell count over the grand total, and reading which total a question wants.
Author note — to cover
Turn a completed table into probabilities: the named cell over the grand total, or over a row or column total only when the wording restricts the group, with fraction, decimal and percentage answers. Both tiers. Formal P(A given B) notation and given-that questions are Higher, on conditional-from-two-way-tables (Combined events). (P1, P6)
- Fluency — direct questions on probabilities from a two-way table, limited to this lesson's stated scope (4 questions).
- Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
- Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
