The probability is just 1/2 that the disc will result with the white side landing up.
There are two sides to the disc. If they are equally likely to happen, then the chance of either side is 1/2. It does not matter which number the flip is.

You can not work out it unless provided initial distance between the house and shoreline.
-1/2 and -2 would be the answer
