Three winning Mega Millions tickets sold

(CBS/AP) RED BUD, Ill. — Lottery ticket-holders in Illinois, Kansas and Maryland each selected the winning numbers for the world record-breaking $640 million Mega Millions jackpot, lottery officials said Saturday.

Illinois' winning ticket was sold in the small town of Red Bud, near St. Louis, and the winner used a quick pick to select the numbers, Illinois Lottery spokesman Mike Lang said.

"This is very exciting, people are extremely happy, and of course everybody wants to know who it is," Denise Metzger, manager of the Motomart where the winning ticket was sold, said Saturday morning. "Hopefully I sold that ticket to someone who comes in every single morning."

Maryland's was sold at a 7-11 in Baltimore County, state lottery officials said.

A winning ticket also was purchased in northeast Kansas, according to the Kansas Lottery website.

Each winning ticket was expected to be worth more than $213 million before taxes, Lang said.

The winning numbers in Friday night's drawing were 02-04-23-38-46, and the Mega Ball 23.

CBS News correspondent Whit Johnson said people were coming into the lucky 7-11 in Baltimore County Saturday morning, gazing at the machine that dispensed the winning ticket.

The store's owner, Johnson said, wasn't allowed to comment, but he could tell she was holding back a huge smile. The store gets a $100,000 bonus for selling a winning ticket.

Carole Everett, director of communications for the Maryland Lottery, said the last time a ticket from the state won a major national jackpot was 2008 when a ticket sold for $24 million.

"We're thrilled," she said. "We're due and excited."

The estimated jackpot dwarfs the previous $390 million record, which was split in 2007 by two winners who bought tickets in Georgia and New Jersey.

Americans spent nearly $1.5 billion for a chance to hit the jackpot, which amounts to a $462 million lump sum and around $347 million after federal tax withholding. With the jackpot odds at 1 in 176 million, it would cost $176 million to buy up every combination. Under that scenario, the strategy would win $171 million less if your state also withholds taxes.

From coast to coast, people stood in line at retail stores Friday for one last chance at striking it rich.

Maribeth Ptak, 31, of Milwaukee, only buys Mega Millions when the jackpot is really big and she bought one on Friday at a Milwaukee grocery store. She said she'd use the money to pay off bills, including school loans, and then she'd donate a good portion to charity.

"I know the odds are really not in my favor, but why not," she said.

Sawnya Castro, 31, of Dallas, bought $50 worth of tickets at a 7-Eleven. She figured she'd use the money to create a rescue society for Great Danes, fix up her grandmother's house, and perhaps even buy a bigger one for herself.

"Not too big -- I don't want that. Too much house to keep with," she said.

Willie Richards, who works for the U.S. Marshals Service at a federal courthouse in Atlanta, figured if there ever was a time to confront astronomical odds, it was when $640 million was at stake. He bought five tickets.

"When it gets as big as it is now, you'd be nuts not to play," he said. "You have to take a chance on Lady Luck."
