Define: Set, Subset, Complement
Question
Define: Set, Subset, Complement
Solution
-
Set: A set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 2, 4, and 6 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {2,4,6}.
-
Subset: A subset is a portion of a set. A set A is said to be a subset of another set B if every element of A is also an element of B. For example, if we have a set B = {1,2,3,4,5} and a set A = {1,2,3}, then A is a subset of B, because every element in A is also in B.
-
Complement: The complement of a set A, often denoted by A', is the set of all elements in the universal set that are not in A. For example, if the universal set U = {1,2,3,4,5,6,7,8,9,10} and the set A = {1,2,3}, then the complement of A (A') is {4,5,6,7,8,9,10}.

It refers to any two sets denoted by A and B such that every element of A is also an element of B then A is called subset of B, written A ⊆ B,
When a set does not contain any element, it is known as __________.
Consider a general set, A, which is a subset of a general set, Ω. Suppose also that B is the complement of A, i.e. B=Ac=Ω∖A.Next let C be a subset of A (i.e. C⊆A) and D be a subset of B (i.e. D⊆B).Tick the most appropriate answer:B∖D=DA∖C=AA∪A=AAll of the above
A set is a collection of objects. It has a few rules that make it a data structure: it is defined by its contents, there is no particular order of storage, there are no duplicate items, sets can have different data types inside it, and can contain other data structures. Which among the following demonstrates the rule where a set is defined by its contents?Group of answer choicesAn unnamed set made out of random stringsA set containing 1, 1.0, ‘c’, and studentsA set labeled as ‘all positive integers’ but has zero (0) in itYour partner is seen kissing another person but when confronted they say : ‘I am cheating, but not on you’.A null set that has a nameA set labeled ‘CITCS 1A students’ but has their instructor inside itYour partner giving you a ‘box of fruits’ containing cabbagesA named set that does not have elementsA set of flowers made up of roses and daisies.A null set that has no name
