Answer 1

please give me thanks

Given, set A = {x : x is a letter in the word FOLLOW} and set B = {y : y is a letter in the word WOLF}.

first of all, we have to represent the set A in roaster form. Set A = {x : x is a letter in the word FOLLOW} e.g., A ={F,O,L,W}.

and also we have to represent the set B in roaster form. Set B = {y : y is a letter in the word WOLF}e.g., B = {W,O,L,F}

concept :- Two set A and B are said to be equal if they have exactly same elements then we say A = B.

it's not matter elements of set A and B do not have significant order, but A and B have same element. hence,  A=B.
