VICTORY LOVES COMPANY

Should you win the jackpot, there's a good chance you'll have to share — and not just with family, friends and Uncle Sam.

The odds of someone winning increase as the ticket sales do. So, too, do the odds of duplicate tickets, especially for people who choose their own numbers rather than letting the computers pick.

Prefer the lucky numbers of seven or 11? You're not alone. How about a loved one's birthday? It's 31 or lower — digits more frequently duplicated than 32 and up. (There are 59 white balls and 35 red balls in the draw).

Norfolk predicts that if there is a winner, there will be multiple ones because mathematical theory shows that numbers have a way of clustering, even at much smaller sample sizes.

If you take 23 random people, there's about a 50-50 chance that at least two will have the same birthday, Norfolk said. Throw choice into the equation — about 20 percent of players typically select their own numbers — and the clusters could be even more defined.

That played out in March, when three tickets from Kansas, Maryland and Illinois split the world-record $656 million Mega Millions jackpot.

A single ticket holds Powerball's current record of $365 million in 2006, shared by several ConAgra Foods Workers in Lincoln, Neb.
