Hi,

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?

Answers we have discussed without agreement:

1) 50%

2) 21,4% ( 6/28)

3) 77%

Thanks for your colaboration
