Post subject:  Bingo

I feel a bit stupid. I printed up some 4x4 bingo cards of numbers. I used 1-18 so I got 16 cards of those numbers jumbled, as one would expect. Now, I did a dummy run with 8 cards i.e. I 'called' the numbers out randomly, covering the numbers on each card if those cards had that number. Four of them 'won'. What did I do wrong? My very un-mathematical mind can't figure it out.
