Question 117334: On Monday, Anthony tiled a 10-by-10 foot area with one-foot square ceramic tiles. A day later, Anthony noticed that two of the one-foot tiles were cracked. If the cracks randomly occurred after the tile was laid, what is the probability that the two cracked tiles share a common edge with each other? In other words, two cracked tiles are next to each other (but not diagnal)?

-----------
Draw a 10 by 10 pattern of 1 ft sq. squares.
Count the number of sides that are shared with
another tile. Divide that number by the total
number of sides in the figure.
