Few, but active (Posted on 2010-10-26) Difficulty: 1 of 5
Few of my friends spent the last weekend in a resort, which was offering inter alia the following activities:
Tennis, swimming, chess and disco.
Each one of my friends participated in two of the above, and every subset consisting of two activities was chosen by one of my buddies.

What number could replace the word "Few" without affecting the truthfulness of my story?

Each subset of two activities was used. The number of sets of 2 activities is C(4,2) = 6

So atleast 6 friends must be there. Since its not specified that each set was used only once any number greater than or equal to 6 can satisfy the line without affecting its truth.
