At school Joe has three friends: Tim, George and Paige. Two of them play football, two play tennis, and two play golf. The friend who doesn't play golf doesn't play tennis and the one who doesn't play football doesn't play golf. Which sports does each person play?
George and Tim play all three sports and Paige plays none. This is assuming girls do not play football. If the school did have a girl's football league all we would know is that one of the three play no sports and the others play all three.
