Exercise files in repository have typo 'Excercises' in name

[donalus]

The exercise files in the repository are all named like "Chapter 1 Excercises.ipynb" instead of "Chapter 1 Exercises.ipynb".

This is typo that I frequently make, so I noticed it when I was posting a message to my students.

could you please let me know, where are the solutions of the exercises?
