CHICAGO — Eight months after a trio of ticket buyers split a $656 million Mega Millions jackpot to set a world lottery record, Powerball is offering up a prize that would be the second highest.
The $500 million jackpot, the largest in Powerball's history, represents a potential life-changing fortune. But before shelling out $2 for a ticket, here are some things to consider:
A GOOD BET: SOMEONE WILL WIN
It's the gambler's mantra: Somebody's gotta win, so why not me?
The first part is true; somebody will win the Powerball jackpot.
Chuck Strutt, executive director of Multi-State Lottery Association, predicts there's about a 60 percent chance it'll happen Wednesday — maybe better if there's a flurry of last-minute ticket purchasers picking unique numbers.
The jackpot already has defied long odds by rolling over 16 consecutive times without anyone hitting the big prize, which now stands at $500 million ($327 million cash value). Strutt puts the odds at around 5 percent there would be no winner in the entire run through Wednesday.
As the drought increases, so too will the chances of it ending on the next draw, because ticket sales spike with a growing jackpot.
Someone will win. Eventually.
A BAD BET: IT'LL BE YOU
It's true to say that you have a better chance of being struck by lightning than winning the Powerball. But that woefully understates the danger of lightning.
Tim Norfolk, a University of Akron mathematics professor who teaches a course on gambling, puts the odds of a lightning strike in a person's lifetime at 1 in 5,000. The odds of winning the Powerball jackpot: 1 in 175 million.
While weather is the go-to analogy for such astronomical odds, Norfolk suggests there are better ones.
For example, you'd have a slightly better chance of randomly picking the name of one specific female in the United States: 1 in 157 million, according to the latest census.
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.
FEELING LUCKY IN A BAD ECONOMY
Gambling experts say a majority of Americans will play some lottery game at least once in a given year.
Clyde Barrow, director of the Center for Policy Analysis at UMass-Dartmouth, says addicted gamblers are less likely to turn to massive jackpot ticket games like Powerball than scratch-off games.
"Scratch-off players are looking for instant gratification and an instant win," Barrow said. "A lot of those people don't like playing lotto because you have to wait. You have to sit on it for a few days."
While it may seem counterintuitive, Barrow says gambling activity often increases as the economy gets worse and people have less disposable income. However, his research — which focused mainly on New England — found the trend reversed in the latest downturn.
"The Great Recession has been so deep and so long, it's suppressed any kind of discretionary spending across the board," said Barrow, who added about the same percentage of people are playing the lottery — they're just buying fewer tickets.
Strutt, Powerball's executive director, said sales largely stayed flat during the peak of the recession in 2008 and 2009, but picked up since.
"Our biggest factor is gas prices," he said. "If people go to a gas station and put 80 bucks of gas in their car, they're not feeling happy to buy a lottery ticket."
It's conceivable you could win Wednesday night's drawing, just not the right one.
In addition to the official one televised nationally from Tallahassee, Fla., there are four practice runs. The reason, Strutt says, is to make sure the machines are running properly and the numbers are being distributed properly.
The balls used in the game are regularly measured, weighed and X-rayed. Then they're locked up in a room that's under 24/7 surveillance. Only the organizers and their auditors have a key.
IS IT A GOOD INVESTMENT?
You already know the answer to that. Yet people play anyway.
Strutt is estimating that there will be $214 million in sales for Wednesday's drawing (up from $140 million from Saturday's drawing).
Half the proceeds go to the prize pool — about a third of that to the big jackpot, with the rest to lower ones, including a new $1 million second prize. The other half goes to the lottery operations in the 42 states plus Washington, D.C., and the Virgin Islands where Powerball is played. This funds charitable efforts such as education, in addition to paying for overhead and compensating winning stores.
Barrow says it's no secret that it's not a prudent investment to regularly buy lottery tickets, but he contends it's a little more defensible as the amount skyrockets.
If the jackpot amount approached $600 million, and if you had the means to buy enough tickets until you won, AND if you could guarantee you wouldn't have to share with anyone, then it might be a wise investment, he said.
That's a lot of ifs, Barrow acknowledges. Still, he says he'll likely join the throngs of ticket buyers.
"For two bucks, it's worth a chance," he said. "What else am I going to do with that $2? I'll just waste it on something else."
