WebJan 28, 2024 · A set is a collection of elements. A set with no elements is still a set and is known as an empty set. A subset is any combination of elements from a set. An empty set is a subset of any set. This means every set has an empty subset. Sets are represented using the notation: {,}. Example: {1,5} is a set. {}, {1}, {5}, & {1,5} are all of its ...
