Rewrite the following statements using the set notation:
(i) a is an element of set A.
(ii) b is not an element of A.
(iii) A is an empty set and B is a nonempty set.
(iv) A number of elements in A is 6.
(v) 0 is a whole number but not a natural number.
(i) Given: a is an element of set A
this means a ∈ A
(ii) Given: b is not an element of A
this means b ∉ A
(iii) Given: A is an empty set
and B is a non – empty set
this means A = ɸ
and B ≠ ɸ
(iv) Given: In set A, total number of elements is 6
This means, |A| = 6
(v) Given: 0 is a whole number but not a natural number
This means 0 ∈ W but 0 ∉ N
