What is the difference between A,D,E,G,H and B,C,F ------and how are they alike

Question

I was helping my sister with her homework and I found this math question that me or my little sister could find the answer too,and I got no stinking clue what it could be. I would love it if some one could tell me the answer so I could help her Thank you so much!!

Answer 1

Different:

A, D, E, G, H has five letters, which is more than the three letters of B, C, F.

A, D, E, G, H starts at the beginning of the alphabet, but B, C, F doesn't.

A, D, E, G, H contains vowels, but B, C, F doesn't.

On a QWERTY keyboard, A,D,E,G,H requires both hands; B,C,F requires only left hand (Note: touch typing)

 

Alike:

Both lists are in alphabetical order (but with letters missing).

Both lists contain only capital English letters (no lower case).

 

Answer 2

If no other other information is available, we can at least say they are two different sets, with no elements in common, and hence their intersection is the empty set.  (But I do not know if that was intent of the question.)

 

A = {A,D,E,G,H}

B = {B,C,F}

 

A∩B = Ø (empty set)
