Demorgan's law states that the complement of the union of two sets is equal to the intersection of their complements and the complement of the intersection o.

Misc 8 Show That A A в B U A B And A U B A A U By a distributive law = a ∩ (b ∪b¯¯¯¯) = a ∩ ( b ∪ b ¯) by a complement law = a ∩ u = a ∩ u. by an identity law = a = a. this answers the question. could you please prove that a ⊆ (a ∩ b) ∪ (a − b) a ⊆ ( a ∩ b) ∪ ( a − b) , that will be more helpful. I know that a∪(b∩c)=(a∪b)∩(a∪c). i feel like i'm supposed to apply this to this question, but i'm really confused by all the terms. so far i have: (a∪b)∩(b∪c)∩(c∪a)=(b∪a)∩(b∪c)∩(c∪a)=b∪(a∩c)∩(c∪a). Solution: by using the a union b formula, we find a u b just by writing all the elements of a and b in one set by avoiding duplicates. thus, by the given venn diagram, a u b = {11, 20, 14, 2, 10, 15, 30}. note: 17, 16, 3, and 18 are neither the elements of a nor the elements of b and hence they are not present in a u b. Let a and b be sets. define the symmetric difference of a and b as a∆b= (a ∪ b) − (a ∩ b). (a) prove that a∆b = (a − b) ∪ (b − a) i tried to start this but am getting really lost. if someone could try to help that would be great.

The a’ u (b ∩ c)’ operation follows the distributive property. in other words, a’ u (b ∩ c)’ = (a’ u b’) ∪ (a’ u c’). this property allows us to distribute the complement operation over the intersection operation within the set expression. absorption. the a’ u (a ∪ b)’ operation demonstrates the absorption property. The union set operations can be visualized from the diagrammatic representation of sets. the rectangular region represents the universal set u and the circular regions the subsets a and b. the shaded portion represents the set name below the diagram. let a and b be the two sets. the union of a and b is the set of all those elements which belong.
