Conditional probability
Use a table, a Venn diagram and a tree to work out the probability of one event when you already know another, see why the order of "given" matters, and meet dependent events.

الدليل
This studio follows Afghan grade 12 chapter 8 (الاحتمال المشروط: P(A given B) = P(A ∩ B) ÷ P(B), and the product rule) and the UK GCSE conditional probability from tables, Venn diagrams and trees.
"Given B" means we already know B happened, so only B is possible: B is the new whole. In a table, look only at the row or column of B.
Common mistakes worked on here: dividing by the grand total, mixing up P(A given B) with P(B given A), ignoring the condition, and treating events as unrelated when one changes the chance of the other.
