Venn diagrams, set notation and conditional probability

By the end you’ll be able to

• Use set notation: universal set $\xi$, union $A \cup B$, intersection $A \cap B$, complement $A'$, and $x \in A$
• Complete and use Venn diagrams (two or three sets) and two-way tables to find probabilities, including with algebraic unknowns
• Calculate conditional probabilities $P(A \mid B)$ from Venn diagrams, two-way tables and tree diagrams (Higher)
