Question

If A is the set of all integers, choose the set B that will make the following statement false.B ⊆ A

B = {1, 2, 3}
B = {2.5, 3.5, 4.5}
B = {0}
B = {−4, −1, 0, 5, 10}

Answer 1

B.

Explanation:

The sets {1, 2, 3}, {0}, {-4, -1, 0, 5, 10} only include integers which makes the statement true. Since they are all integers they are all subsets.

Answer {2.5, 3.5, 4.5} does not include integers so therefore it is not a subset making the statement false.
