Make a conjecture about the number that would exist if it were further extended to have 7 elements, according to the same principle that no one element is "better" than any other. WebIn standard set theory, due to the Axiom of Extensionality, it has 4 elements. But in multiset theory, it has 5 (that is, its cardinal is 5). A multised may have repeated elements. So, the …

WebUnion, Intersection, and Complement. The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. More formally, x ∊ A ⋃ B if x ∈ A or x ∈ B (or both) The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B. More formally, x ∈ A ⋂ B if x ∈ A and x ∈ B. WebJul 7, 2024 · It is obvious that {1, 2, 7} ⊆ {1, 2, 3, 6, 7, 9} because all three elements 1, 2, and 7 from the set on the left also appear as elements in the set on the right. Meanwhile, {1, 2, 7} ⊈ {1, 2, 3, 6, 8, 9} because 7 belongs to the first set but not the second.
