Question

2. In the following, state whether A= B or not:
(i) A = {a,b,c,d}B = {d,c, b,a}
Solution:
(ii) A = {4,8, 12, 16 } B = {8,4, 16, 18)
Solution:​

Answer 1

Answer:

(i) A = {a,b,c,d}, B = {d,c, b,a}

Here, A = B, beacuse all the elements in A are present in B.

(ii) A = {4,8, 12, 16 }, B = {8,4, 16, 18)

Here, A is not equal to B, beacuse the elements of both the sets are not same.

Extra Information :

• Set is a collection of objects or elements that are well defined.
• The elements are written inside the curly brackets.
• The set name is always written in capital.
• Equal sets are sets with same elements.
• Equivalent sets are sets with same number of elements.
• The number of elements is called as cardinality of the set.
• A set is said to be a subset of another set, when the elements of one set is also an element of another set.
