Another activity that can be characterized on sets An and B is the distinction of the sets, meant by

A B.

Here is the conventional meaning of the distinction of sets An and B.

AB = {x | xA and xB}

Hence

A B

is the arrangement of components that have a place with A however not to B. For example, let

,//18//A = {1, 2, 3, 7, 8}

also,

B = {2, 7, 11}.

At that point

A B = {1, 3, 8}.

Decide the distinction, given that

U = {1, 2, 3, 4, 5, 6, 7, 8, 9},

A = {2, 4, 6, 8},

also,

B = {2, 3, 4, 7}.
