WebThus the final result must be countable. 11/ (i) The union of two countably infinite sets must always be countably infinite per the analysis in the preceding question. (Obviously the cardinality of a union of two sets is always greater than or equal to the cardinality of each of the sets, so it can’t be finite.) WebMay 20, 2024 · Definition: Subset. A is a subset of B, (denoted A ⊆ B ), if every element of A is also an element of B. TEMPLATE To prove A ⊆ B: We NEED to show If x ∈ A then x ∈ B. Example 2.1. 1: Let A be a set. Then ∅ and A are subsets of A. So A, ∅ ⊆ A.
WebThe cardinality of a set is the number of elements in it if it is a finite set. The cardinality of an infinite countable set is denoted by N0 (a symbol called aleph null). ... Let us consider two sets A and B (finite or infinite). Then: n(A) = n(B) if there can be a bijection (both one-one and onto) from A → B. Web6)We can use the following formula to find the cardinality of the union of two sets: A ∪ B = A + B - A ∩ B We can also use the formula for the cardinality of the complement of a set: U \ B = U - B where U is the universal set. First, let's find the cardinality of B …
