Support Establish that P(A|B) = (A∩B)/(B) when all outcomes are equally likely by restricting the sample space and event space, and hence P(A|B) = (P(A∩B))/(P(B)), provided (B)≠0

Resources for the prerequisite content of this dot point: earlier-stage (or earlier sub-level) dot points in the same strand that students usually need first. Use these to fill gaps before or alongside the core lesson.

Prerequisite links are draft mappings generated from the syllabus structure (earlier stage, same strand, closest content). They are being reviewed by teachers. Spot a poor match? Tell us.
