If set d is not the empty set but is a subset of set e, then which of the following is true? d ∩ e = d d ∩ e = e d ∩ e = ∅

D intersect E=D (the first one you have)

Step-by-step explanation:

D is a subset of E

That means all the elements in D are also in E

So the intersection of D and E is D.

The first thing you wrote is correct, that is, D intersect E=D is right

=D

Step-by-step explanation:

We are given that D is not empty set but D is a subset of set E.

We have to find the true statement.

D is  a subset of set E

Therefore,

Intersection: It is the set of common  elements of two sets.

Therefore,=D

Because E contains all elements of D .

Hence, Option A is true.

yes yes yes yes yes yes yes yes yes
