Determining if a Set is a Subset of Another Set

To ascertain whether one set is a subset of another, we need to verify if all the components of the initial set are also present in the secondary set. If this holds true, then we can conclude that the initial set is indeed a subset of the secondary set. This relationship can be symbolized as A ⊆ B. It's important to note that both identical and non-identical sets can qualify as subsets.
