Question

Which is a subset of {1, 2, 4, 5, 6}?

{0, 1, 2}


{3, 4}


{5, 6, 7}


{2, 6}


(believe its the last one but just want to make sure)

Answer 1

{2, 6}

Explanation:

Subset: A subset is a set of which all the element are contained or can be find in the universal set.

From the question above,

μ = {1,2,4,5,6}

* The first option {0,1,2} is wrong because 0 is not contained in the universal set.

* The second option {3,4} is wrong because, 3 is not contained in the universal set.

* The third option {5,6,7} is wrong because 7 is not contained in the universal set.

* The last option {2,6} is correct because all of the element of the set are contained in the universal set, and as such makes it a subset.

Hence the subset of {1,2,4,5,6} is {2, 6}
