There was a show about a girl who claimed to have 'xray eyes' and diagnose a patient just by looking at them. Csicop did a test with 7 subjects, each with a particular ailment; she had to match each subject with a list of 7 ailments she was given. Csicop said that if she got 5 of 7 correct, they would admit that she had a definite abililty of some kind. They said that the odds of getting 5 right were 250:1. She ended up getting 4 correct. But they didn't mention the odds of getting 4. What are the odds?
