1.	If A is a subset of B and B is a subset of C, then cardinality of A U B U C is equal to ____________(a) Cardinality of C(b) Cardinality of B(c) Cardinality of A(d) None of the mentionedThe question was asked in an international level competition.The question is from Cardinality of Sets topic in portion Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics
Answer» CORRECT choice is (a) CARDINALITY of C To EXPLAIN: A U B U C = C, since a, b are subsets to C.
