If D = {w, h, y} and E = {n, o, t} then answer the following:
(a) How many possible one-to-one correspondences are there between sets D and E?
---------
Corresponding to w you have 3 choices
Corresponding to h you can 2 choices
Corresponding to y you have 1 choice
-------------
Answer 3! = 6 possible 1-1 correspondences.
====================================================
(b) How many elements are in the Cartesian product D X E?
All possible ordered pairs (d,e) where d is from D and e is from E.
# = 3*3 = 9 ordered pairs
