Which of the following sets are equal

Question

A={O L W D }

B={FOLLOW}

B={WOLF}

C={FLOW}

Answer 1

To be equal, they must both contain the exact same members.  Note that sets B and C both contain 1 each of the letters F, L, O, and W.  In that sense, they are equal sets, apart from the order in which their members are listed.  However, if you meant the members of these sets to be complete words rather than letters, then one set has the word "flow" and the other set has the word "wolf", and hence they do not have the same members, and therefore are not equal sets.  It is a matter of whether the members of the set are the letters or complete words. Which one did you intend in the question?
