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 is a subset of E,
so what do they have in common?

Answer 2

What elements do both sets contain?

Answer 3

o its the middle one?

Answer 4

Both of them contain the set E?
No.

Look at the diagram I drew, clearly D does not have E inside of it.

Answer 5

D is a subset of E,
so D is contained within E.

E has D inside of it.
And D has D inside of itself, nothing special there.

So we can see that they both contain all of D, yes?

Answer 6

so its the first one?

Answer 7

yes..

Answer 8
