Drills
Finding conditional probabilities by restricting to the cases where the condition holds.
Author note — to cover (Higher)
- Fluency — P(B given A) from small two-way tables, dividing a cell by the row or column the condition names (4 questions).
- Diagrams — conditional probabilities read from completed Venn diagrams and tree diagrams, as exact fractions (4 questions).
- Reversed conditions — P(A given B) and P(B given A) from the same data, catching the assumption that they are equal (4 questions).
