EQUAL SETS -
Two sets A and B are said to be equal iff they have exactly the same elements and we write A = B. Otherwise, the sets are said to be unequal and we write A ≠ B.
- wherein
eg. A= {3,2,1,4} and B= {2,3,4,1}
Clearly and are equal sets since they have exact same elements.
Option 1)
is a set of letters of ALLOY and is a set of letters of LOYAL.
