Problem 7. Imagine a square grid with bottom left point at (0,0) and top right point at (8, 8), and consider all possible paths from (0,0) to (8,8) which use only North and East steps. What is the probability that a path goes through the point (4, 4)? How is this problem similar to the problem involving coin tosses?
