I am having trouble understanding how to solve this problem. I found an answer, about 74.2%, but I am not sure if that is correct. Any help would be greatly appreciated!
A chess board has 64 squares,
32 white and 32 black, and is played
with 16 black and 16 white pieces. If all the pieces are placed randomly on
the board, what is the probability of two
white knights being on black squares or
a black bishop being on a black square?
