Chessboard Coin (Posted on 2004-10-08) Difficulty: 2 of 5
I've a chessboard of side 80cm.

You've a coin of diameter 2cm, and you throw it on to the chessboard. The center of the coin falls somewhere on the chessboard.

What is the likelihood that the coin is completely within a white square?

(In reply to re(4): Dumb Question by jduval)

It has been stated in paragrqaph 2 that the centre of the coin falls somewhere on the board, i think this means that one face of the coin is touching the board, which in turn takesout the possibility of falling on edge.
I got the answer as .32 or 32%
Which agrees with the answer that has already been posted by others
