Eight pawns are placed at random on an 8 × 8 chessboard, with all configurations equally likely. What is the probability of each of these events:

1. The pawns are in a straight line. (Don’t forget the diagonals!)

2. All the pawns occupy white squares.

3. No two pawns share the same row.

4. Now two pawns share the same row or the same column.

One rook is placed in some unit squares of a 100 × 100 chessboard. Castles in the same row or in the same column, with no other castles threaten each other. Regardless of the number and location of the castles, if any two castles that threaten each other can be in different colors, what is the smallest value of the number n that can always be painted in one of n colors?

C Programming Language. A chessboard consists of 8 squares x 8 squares for a total of 64 squares. The squares of the chessboard are identified, from the perspective of the player with the white pieces, by the letters a – h for the 8 columns or files (starting from that player’s left), and 1 – 8 for the 8 rows or ranks (starting closest to that player). One of the chess pieces, the knight, can move in any direction by...
