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

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, …

The complement of a universal set is an empty set.

Which of the following create an empty set?A. s={}B. s=[]C. s=set([‘’])D. s=set()E. None of the above
