Question: If n(A ∪ B) = 97 and n(A) = n(B) = 64, find n(A ∩ B).
Web28 jul. 2024 · The question is incomplete. It should be: If n (A)=36, n (B)=10, n (A∪B)=40, and n (A')=27. Find n (∪) and n (A∩B) Find n (U) n (A') = n (∪) - n (A) 27 = n (∪) - 36. n … Webif A ⊆ B, then A ∪ B = B. For example, if A = {2n n ∈ ℕ} and B is the set of integers, then A ∪ B = B, since set A is the set of positive even integers, which is a subset of all integers. … WebX∩(A∪B) = (X∩A)∪(X∩B). Assume that A∪B= E. Let X,Y ⊆Ebe such that f(X) = f(Y). We have X= X∩E= X∩(A∪B) = (X∩A)∪(X∩B) = (Y∩A)∪(Y∩B) = Y. fis thus injective. To prove the converse, consider its contrapositive. Assume A∪B⊆ / E. Let x∈E\(A∪B). We have f({x}) = (∅,∅) = f(∅) and {x}6= ∅. Hence, fis not ... saying only believe half of what you see
