Question

Which is a subset of [1,2,4,5,6]? A. [0,1,2] B. [3,4] C. [5,6,7] D. [2,6]

Answer 1

Answer: D, [2,6])

Step-by-step explanation

Let us start by explaining what a subset means. A subset of a set is a a set(usually a smaller set) that contains contains elements which are all members or elements of the main set. This means that all the elements in the subset are contained in the main set. Usually, all the elements of the subset are contained in the main set but all the elements in the main set are not contained in the subset

The given set of numbers is

[1,2,4,5,6]

From the options given, all the elements in the subset, [2,6] are contained in the main set, [1,2,4,5,6].

So option D is the subset.

The subsets in the other options has elements that are not in the main set.
