Question

Let set C = {1, 2, 3, 4, 5, 6, 7, 8} and set D = {2, 4, 6, 8}

Which notation shows the relationship between set C and set D?

Answer 1

you will want to review the definitions of the notations most likely, but pick the onw you think it is and we will correct you if your mistaken

Answer 2

I believe it would be C ∩ D

Answer 3

A U B (A union B) = 'either A or B occurs or both occur'
A n B (A intersection B) = 'both A and B occur'
(A is a subset of B) = 'if A occurs, so does B'

Those are the definitions.

Answer 4

Oh ok it's C ⊆ D. Because if C occurs so does D. The numbers from set D are in set C so there it is C ⊆ D.

Answer 5

D is contained in C;

\[D\subset C \]
