1.We continued with Permutations & Combinations, picking up Permutations in a Circle and applying all of our techniques (grouping, slotting, complement and cases) in consolidated questions. For Permutations in a Circle, important considerations include: is the circle unordered (n-1)! or ordered? Choose How do we treat ordered circles when grouping or slotting is involved? (1. treat as unordered circle 2. multiply by number of seats) We also started on Probability, recapping ideas from secondary school, including Venn diagrams.
