A Statistics professor comes home to find that all four of his children got white team shirts from soccer camp this year. He concludes that this year, unlike other years, the camp must not be using a variety of colors. But then he finds out that in each child s age group there are 4 teams, only 1 of which wears white shirts. Each child just happened to get on the white team at random.
