clothing.
each of the articles of clothing is made up of two articles different in
color from one another. Blah....Blah
One question is "If no two outfits contain the same color combination but
EACH contains at least one navy item, which one of the following is a
complete and accurate list of the possible combinations for outfit X"
The EACH in question means each of 3, right?
