A wireless grid consists of 72 sensors located at points (ij) in the xy-plane such that i is in {0,1,2,3,4,5,6,7,8} and j is in {0,1,2,3,4,5,6,7). The sensor node located at point (0,0) needs to send a message to a node located at (8,7). The messages are sent to the destination by going from each sensor to a neighboring sensor located above or to the right. That is to say, we will avoid backtracking - we can only move right or up. How many different paths are there for sending a message from (0,0) to (8,7)? Please show your work.
