C959: Discrete Math 1 questions with 100% correct answers Set Difference - answer A - B, the set containing those elements that are in A but not in B Set Symmetric Difference - answer A ⊕ B: the set of elements that are a member of exactly one of A and B, but not both. An alternative definition of the symmetric difference operation is: A ⊕ B = ( A - B ) ∪ ( B - A ) Set Complement - answer the set of all elements in U that are not elements of A. An alternative definition o...
