Hi, I have a problem which I do not know the answer to. Two ants start on the origin of a coordinate grid, and keep going right and up until they reach (5,5), and can not go farther than (5,5). Every time they get to a new point, the 1st ant puts a blue dot, and the second one puts a red dot. What is the probability that there will be 5 purple dots? The Ants DO put a purple dot at the origin and at (5,5).
