More On Opposite pairs

In the previous post, we noted that colors come in pairs. Here we generalize the concept of pairs. Consider a set of n items

A = {1, 2, 3,……,n}

We define on A the following collection

T = {(X, Y)| X is a subset of A, and Y is the complement of X in A}.

We can explain it by the following set of fruits

A = {b, o, g}

where b = banana, o = orange, and g = grapes

T = {(no fruit, all fruits), ({b},{o,r}), ({o},{b. g}), ({g},{b, o})}
