(a ∪ b) ∪ c = a ∪ (b ∪ c), (a ∩ b) ∩ c = a ∩ (b ∩ c). Web for example, if a = {1, 3, 5, 7} and b = {1, 2, 4, 6, 7} then a ∪ b = {1, 2, 3, 4, 5, 6, 7}. Web for example, if the union of sets = {3, 2, 1, 2, 3}, then it has cardinality 3. If set a is a subset of set b, then the union of the two sets is set b. The symbol for the union of sets is ∪''. Solved examples of union of sets. Web the following properties hold for any sets a, b, and c in a universal set u. Web it refers to the collection of all the elements in individual subsets. A more elaborate example (involving two infinite sets) is: A = { x is an even integer larger than 1} b = { x is an odd integer larger than 1}
If set a is a subset of set b, then the union of the two sets is set b. A = { x is an even integer larger than 1} b = { x is an odd integer larger than 1} (a ∪ b) ∪ c = a ∪ (b ∪ c), (a ∩ b) ∩ c = a ∩ (b ∩ c). A ∪ b = b ∪ a, a ∩ b = b ∩ a. The symbol for the union of sets is ∪''. A more elaborate example (involving two infinite sets) is: For example, if a = {2n|n ∈ ℕ} and b. Web the following properties hold for any sets a, b, and c in a universal set u. If set a is a subset of set b, then the union of the two sets is set b. Web it refers to the collection of all the elements in individual subsets. Web for example, if a = {1, 3, 5, 7} and b = {1, 2, 4, 6, 7} then a ∪ b = {1, 2, 3, 4, 5, 6, 7}.
