I have a discussion with my friends about the next games.
As you know for the next step there are 4 British teams, 2 Spanish teams, 1 Germany and 1 Portuguese.
The problem is the following.
What is the probability of at least to have one game between British teams?
The problem can be reduced to 4 White balls + 4 Black balls in a bag?
