Question

Select all of the following true statements if R = real numbers, I = integers, and W = {0, 1, 2, ...}.
W ⊂ I
R ⊂ W
0 ∈ I
Ø ⊂ R
{0, 1, 2, ...} ⊆ W
-2 ∈ W

Answer 1

I have the definition : A is a subset of B iff for all \[x \in A\] then \[x \in B\]. Check your question with this definition.

Answer 2

all but 0 ∈ I
0 ∈ I
{0, 1, 2, ...} ⊆ W
-2 ∈ W

Answer 3

I see the result are A, C, D, E
