Set: Collection of well-defined distinct objects. A ∪ B = union (all elements from A or B). A ∩ B = intersection (common elements).
n(A ∪ B) = n(A) + n(B) - n(A ∩ B). For three sets: n(A∪B∪C) = n(A)+n(B)+n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C).
A - B = elements in A but not B. A' (complement) = elements NOT in A.
Venn diagram: Shows relationships between sets using overlapping circles. Use for word problems about surveys.
