Disk Toss on a Grid (Posted on 2016-07-08) Difficulty: 3 of 5
A disk that is 1 cm in diameter is tossed onto a 6x6 grid of squares with each square having side length 1.25 cm.

A disk is in a winning position if no part of it touches or crosses a grid line- otherwise it is in a losing position

The disk is tossed and it lands in a random position so that no part of it is outside the grid.

What is the probability that the disk is in a winning position?
