Imagine that there are 2n people in front of a box office. Each of n of these people

holds a 10 dollar bill and each of the other n people holds a 20 dollar bill. The ticket

costs 10 dollars and at the beginning the box office has no cash. How many ways are there to line up the 2n people if we want to make sure the box office never runs out of change?
