Default Re: Probabilty Riddles

I kind of like this one (not too hard, though)....

Young Hans leaves each day from school and walks to the bus stop. Two different bus lines pass by this stop, one that goes to the airport and one that goes to the harbor. Hans likes to watch both the planes and the ships, so he just gets on the first bus that arrives.

Hans arrives at the bus stop at random time between 3 and 4 each day.
Each bus makes exactly 3 stops at the bus stop between 3 and 4 each day.
Yet, at the end of the year, Hans ended up going to the harbor 12 times as often as he want to the airport.

How can this be?
