What to Focus On

  • Sets are collections of distinct objects or elements
  • Universal set contains all elements being considered
  • Union combines elements from multiple sets

  • Two-set Venn diagram has four distinct regions
  • Formula: Total = A + B - (A ∩ B)
  • Intersection must be subtracted to avoid double counting

  • Three-set Venn diagram creates eight distinct regions
  • Inclusion-exclusion principle prevents multiple counting
  • Formula: A ∪ B ∪ C = A + B + C - A∩B - A∩C - B∩C + A∩B∩C

Common Mistakes to Avoid

For two sets A and B, the total number who have at least one attribute is simply A + B

In three-set problems, you subtract all three intersections: A + B + C - A∩B - B∩C - A∩C

People who like 'A and B only' includes everyone who likes both A and B
