Probability Questions and Puzzles

Some parts of my spare time are filled with creating and collecting probability theory questions and puzzles. I maintain a list of probability questions which you can find below. Although short, some of these are non-trivial. I hope that trained probabilists still find some of them challenging.

I'm also using them in my teaching of 1st year undergraduate students. I'm always interested in alternative solutions, extensions or new questions so if you happen to solve them or have suggestions for new puzzles then please do contact me.
