If the system is random then that sequence of number is just as likely as any other possible sequence of numbers randomly drawn. The fact that 20 people won with those numbers says a lot more about the human fixation with simple sequences than possible fraud.Tuesday's PowerBall lottery saw the numbers five, six, seven, eight and nine drawn, while the PowerBall itself was, you have guessed it, 10.

The organizers say the sequence is often picked. But some have alleged a scam and an investigation is under way.
