perplexus.info :: Probability : Chessboard Coin

Chessboard Coin (Posted on 2004-10-08)

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?

Well, I did label my question correctly, then!

Turning things around, then, the answer will change if the coin is required to land totally on the board?
