If A and B are finite sets which of the following is the correct statement?

WebIf A and B are two finite sets, then n (A) + n (B) is equal to n (A ∪ B) + n (A ∩ B). Explanation: Since n (A ∪ B) = n (A) + n (B) – n (A ∩ B) So n (A) + n (B) = n (A ∪ B) + n (A ∩ B) Concept: Types of Sets - Finite and Infinite Sets Report Error Is there an error in this question or solution?

SOLVED:Prove that if A and B are finite sets with A = B

Webto this problem. We have been told that we have two sets A and B needs a finite sets. In other words, there is a fixed number of elements within each set and the card in ality of the two sets are equal. So the number of elements and set A is equal to the number of elements and set B. We're also told we have a function going from A to B. Web(a) By Exercise 9, if AB is invertible, then so are A and B. Clearly AB = I n is invertible. Therefore our conclusion follows immediately. (b)WeneedtoshowthatA = B−1, whichmeansthatAB = BA = I n. AB = I n is given to us by assumption, so it suffices to show BA = I n: Multiplying A on the right of I n = AB, we get A = I nA = ABA. 1 Webx ∈ A, then x /∈ B (because otherwise x ∈ A ∩ B), so x ∈ A \ B. If x /∈ A, then by assumption x ∈ B, so x ∈ B\A. In either case, x ∈ (A\B)∪(B\A). This shows (A ∪ B) \ (A ∩ B) ⊆ x ∈ (A \ B) ∪ (B \ A). Together with the first part this shows the claimed set equality. 1.1.4 (d) Prove that (A∩B)×C = (A×C)∩(B ×C ... facebook bolivar church of god
