Post a New Question

Posted by on .

In a chess variant, a "lord" can move one space at a time, either upward, or to the right, or diagonally upward and to the right. How many ways are there for a lord to move from the bottom left to top right corner of the 8 by 8 chessboard?


Thanks in advance for helping me!

  • A probability question i think - ,

    Each move advances either upward or rightward or both. If there are n diagonal moves, then there are 14-n up or right moves. So, there may be 0 to 7 diagonal moves, and the rest can be chosen in two ways.

    so, there are

    (0+2^14) + (1+2^12) + (2+2^10) + ... + (7+0) = 21872

    Here, make a chart that cascades to the upper-right-most square. Kinda like Pascal's Triangle.
