14. Problem Of the Day-TPS Jeanine leaves the library and walks toward the pool at the same time as Miguel leaves the pool and walks toward the library. Neither person follows a particular route, except that both are always moving toward their destination. What is the probability that they will meet if they both walk at the same rate?

15. Solving the POD… If the two will meet that will happen at one of the points on the diagonal. Now you calculate the probabilities of meeting at each of the points on the diagonal and add them up. Share your solutions and how you solved the problem.
