2016 UNCO Math Contest II Problems/Problem 9
Problem
Chess Masters
Four identical white pawns and four identical black pawns are to be placed on a standard
8 × 8, two-colored chessboard.
How many distinct arrangements of the colored pawns on the colored board are possible?
No two pawns occupy the same square. The color of a pawn need not match the color of the square it occupies, but it might. You may give your answer as a formula involving factorials or combinations: you are not asked to compute the number.
