Step : Check whether the given pair of sets are equal or equivalent
Given:
A = set of letters of word ‘FOLLOW’
={ F,O,L,W}
And B = set of letters of the word ‘WOLF’
={W,O,L,F}
∴ Both the sets have same elements.
And we know that two sets are said to be equal, if the elements of both the sets are same.
Hence, the given pair of sets are equal set.
