     duced earlier, we might then say that black and white squares are in comple-
     mentary distribution on a chess-board. By this we mean two things: firstly,
     black squares and white squares occupy different positions on the board: and
     secondly, the black and white squares complement each other in the sense that
     the black squares together with the white squares comprise the total set of 64
     squares found on the board (i.e. there is no square on the board which is not
     either black or white).
