Key Topics to Revise

1

Representation of Sets

  • A set is a collection of well-defined objects called elements or members
  • Sets are denoted by capital letters (A, B, C) and elements by small letters (a, b, c)
  • Three methods of representation: Roster method, Set-builder method, and Venn diagrams
2

Types of Sets and Intervals

  • Empty set (∅): Contains no elements, n(∅) = 0
  • Singleton set: Contains exactly one element
  • Finite set: Counting process ends; Infinite set: Never-ending elements
3

Set Operations

  • Union (A ∪ B): Elements in A or B or both
  • Intersection (A ∩ B): Elements common to both A and B
  • Complement (A'): Elements in universal set but not in A
4

Practical Problem Solving with Sets

  • Use systematic approach: identify sets, given information, and required answer
  • Venn diagrams are powerful tools for visualization
