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
