WebA − ( B ∩ C) = ( A − B) ∪ ( B − C) proof. I know that by definition must be a double containment Y ⊂ Z and Z ⊂ Y. By drawing Venn diagrams, I believe that equality is not true. so I want to do a containment failure, in particular this Z ⊂ Y, and that this failure should deny the implication that says if x ∈ Y then x ∈ Z if I ...

WebJan 17, 2024 · The latter condition means that either x ∉ B or x ∉ C (since it does not belong to both B and C ). Thus either x ∈ A ∖ B or x ∈ A ∖ C. That is, x ∈ ( A ∖ B) ∪ ( A ∖ C). Look at the implication that was just proved: x ∈ A ∖ ( B ∩ C) x ∈ ( A ∖ B) ∪ ( A ∖ C). This is precisely the meaning of A ∖ ( B ∩ C) ⊆ ... WebNov 4, 2016 · Thus A-(B-C)>=A-B . A-(B-C)-nullset>=A-B-C similarly. It is easily shown when we have one strict inequality between B-C and B or the nullset and C our final inequality is strict and the theorem fails. When we have no such strict inequality by antisymmetry of <= the equation holds. That is, when C is disjoint from B and C is not the … WebMar 23, 2016 · 2. Incidentally, you can still proceed by contradiction. Suppose A ⊆ C and B ⊆ C, but somehow A ∪ B ⊈ C. Then there must be an element x ∈ A ∪ B such that x ∉ C. There are two possibilities: either x ∈ A or x ∈ B (or both are true). If x ∈ A, then x ∈ C, by the premise. But if x ∈ B, then also x ∈ C, again by premise. cinnyathome
