Suppose C is a subset of D and D is a Subset of C.

If n(c)=5,find n(D)
what other relationship exists between C and D

  • Elementary Math for Educator -

    If C ⊂ D ∪ D ⊂ C
    it implies C = D.
    Thus if the cardinality of C is 5, the cardinality of D is also 5.
    The other relationship is, as mentioned above, C = D.
