Question

1. Many people believe that when a horse races, the horse has a better chance of winning if its starting line-up position is closer to the rail on the inside of the track. The starting position of 1 is the lane closest to the inside rail, followed by position 2, and so on, with position 8 being the outside lane. The table below lists the number of wins for horses in the different starting positions: Based On Data From The New York Post.
