Hello! I would like some help for the following problem:
We have 50 teams and we want to divide them in groups of 10 teams each, but we want to prevent two teams to be in the same group for more than once;
How many groups we can make?
For example, if we have 5 letters A B C D E and we want to devide them in groups of 3 then we have only 2 groups: (A B C) and (A D E)
we dont wont both (A B C) and (A B D) because A and B is allready both in the first group.
Thank You and sorry about my English
