Given:
Total students to board the Hogwarts Express = 100 students
The first student occupies the wrong seat.
Each student occupies the allocated seat (if available) if not, he chooses a seat at random.
Determine the chance that the last passenger will get to his seat:
1/99 = 0.01 * 100 = 1.01%

Explanation:
In 1854, Sen. Stephen Douglas forced the Kansas-Nebraska Act through Congress. The bill, which repealed the Missouri Compromise of 1820, also opened up a good portion of the Midwest to the possible expansion of slavery.
Douglas' political rival, former Illinois Congressman Abraham Lincoln, was enraged by the bill. He scheduled three public speeches in the fall of 1854, in response. The longest of those speeches — known as the Peoria Speech — took three hours to deliver. In it, Lincoln aired his grievances over Douglas' bill and outlined his moral, economic, political and legal arguments against slavery.
But like many Americans, Lincoln was unsure what to do once slavery ended.
"Lincoln said during the Civil War that he had always seen slavery as unjust. He said he couldn't remember when he didn't think that way — and there's no reason to doubt the accuracy or sincerity of that statement," explains historian Eric Foner. "The problem arises with the next question: What do you do with slavery, given that it's unjust? Lincoln took a very long time to try to figure out exactly what steps ought to be taken."
