She just randomly resorted them between A and B. She did that a thousand times. The first time, the second time, the third time, and she does this 1,000 times. I'm assuming she used some type of a computer program to do it. Each time, once again, she just took the data that she had and she just rearranged it. She just reshuffled it. Maybe A on one day, maybe it gets this 18, maybe it gets the 25, maybe it gets a 30.
