Question

Let A = set of letters in word 'follow'.

And B = set of letters in the word 'wolf ' .

show that A=B

Answer 1

Clearly , we have

A = { F , L , O , W } .

And,

B = { W , O , L , F }.

Clearly , A and B have exactly same elements.

So,

A = B.

Answer 2

Heya!
--------

-----------------------------------------------------------------------------------------------------

▪A = { Set of letters in the word Follow }

➡Writing it in Roaster form ,


✔A = { F , O , L , W }----------------------(1)

[ This is because repetition is not allowed in a set ]


▪B = { Set of letters in Wolf }

➡Writing its Elements

✔B = { W , O , L , F }----------------------(2)


From (1) and (2)


▪Elements of A = Elements of B


➡A = B
