Answer:

What are the proper subsets of ABCD?

Listing Proper Subsets: List all the proper subsets of {a, b, c}. Example: The set {a, b, c} has 7 proper subsets. They are: ∅, {a}, {b}, {c}, {a, b}, {a, c}, and {b, c}.

Step-by-step explanation:

Example: The set {a, b, c} has eight subsets. They are: ∅, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, and {a, b, c}. Proper Subset: A proper subset is a special type of subset. There are two requirements for set A to be a proper subset of set B.
