A = {1, 2, 3, 4}, B = {2, 4, 6, 8}, C = ℤ, D = {a, b, c}, E = {3, 2, 1} Which sets are equal? Which sets are equivalent? Which sets are subsets or proper subsets? How many subsets and proper subsets does A have?

A = {1, 2, 3, 4}, U = {x | x ∈ℕ and x < 10} Find n(A’). Describe A in set-builder notation (2 ways).

True or False: 𝐴∩𝐵⊆𝐶∪∅ Describe 𝐴′∩(𝐵∪𝐶)′ using a Venn Diagram and list all elements in that set. Also make a cardinality Venn Diagram.

Describe the shaded area.
