When a set does not contain any element, it is known as __________.

What classification of set that contains no elements. It is denoted by ∅.Universal SetEqual SetNull SetFinite Set

The __________ contains all the objects or elements under consideration and the empty set, sometimes called the null set, is the set that contains no elements

The following set notation will be used:• n(A) Number of elements in set A• ∈ “… is an element of …”• ∉ “… is not an element of …”• A′ Complement of set A• ∅ The empty set• Universal set• A ⊆ B A is a subset of B• A ⊈ B A is not a subset of B• A ∪ B Union of A and B• A ∩ B Intersection of A and B.Example definition of sets:A = {x: x is a natural number}B = {(x, y): y = mx + c}C = {x: a ⩽ x ⩽ b}D = {a, b, c, …

A. Identify the term described in each statement.__________ 1. It is a set that contains all elements under consideration and is denoted by thesymbol U.__________ 2. The symbol that denotes the difference between set A and set B.__________ 3. It is a set that contains all elements in the universal set that are not in the givenset.__________ 4. It is a set that contains all common elements of the given sets.__________ 5. It is a set of all combined elements of the given sets

If A = {1, 2, 3, 4, 5} , B = {a, b, c, d, e} and C = { -, +, x, @, *} , then which of the following is the not the element of set (A x B x C)?
