4 people, Richard, Dinesh, Erlich and Gilfoyle (in that order) sit around a desk. They have to code up a project on a laptop that Richard holds. Richard decides that he will pass a laptop around the table by flipping a coin repeatedly. If the coin lands on Heads, then the laptop moves to the right. If the coin lands on Tails, then the laptop moves to the left. The person who has to code up the project is the last person in the team who has touched the laptop.
Who is most likely to have to code up the project?
Note: Richard has touched the laptop at the start.
