Formula Sheet — Sets

Important formulas and equations from Sets for CUET (UG) Mathematics.

Formulas — Sets

Set Representations and Basic Concepts

A = {x : P(x)}
n(P(A)) = 2^n

Subsets and Intervals

Number of proper subsets = 2^n - 1
Length of interval = b - a

Operations on Sets

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
n(A ∪ B ∪ C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)
n(A - B) = n(A) - n(A ∩ B)
n(A Δ B) = n(A) + n(B) - 2n(A ∩ B)

Advanced Counting Formulas

Exactly two sets = n(A∩B) + n(B∩C) + n(A∩C) - 3n(A∩B∩C)
Exactly one set = n(A) + n(B) + n(C) - 2[n(A∩B) + n(B∩C) + n(A∩C)] + 3n(A∩B∩C)
n(A' ∪ B') = n(U) - n(A ∩ B)
n(A' ∩ B') = n(U) - n(A ∪ B)
