Question

If set D is a subset of set E, then which of the following is true?
D ∩ E = D
D ∩ E = E
D ∩ E = Ø

Answer 1

D ∩ E = D

Answer 2

@vamgadu please provide an explanation. Don't just post the answer.
At least provide an example.

Answer 3

For example if
D={1,2,3}
And
E={1,2,3,4}
Then D is a subset of E

And the intersection of them is what elements they have in common

Answer 4

So
\[D \cap E =\{1,2,3\}=D \]

Answer 5

the intersection is the common part of the two circles in the venn diagram
which is D
