500M Reasons to Dream About the Powerball Jackpot

The Powerball jackpot has climbed to half a billion dollars, making tonight's drawing the fifth largest prize in U.S. history.

That jackpot, which has a cash value of $337.8 million, has been growing for the past two months, gradually increasing since starting at $40 million.

The lottery drawing offers a chance for people to dream. Robin Leach, the former host of "The Lifestyles of the Rich and Famous," said he's buying a ticket.

"I think I'd buy a plane larger than Floyd Mayweather['s], I'd buy a boat larger than Larry Ellison['s], and I would probably give the rest to charity," he said.

According to Johnny Avello, the "wizard of odds" at Wynn Las Vegas, the chances of winning are about 175 million to one.

"You're more likely to win an Academy Award and get struck by lightning," Avello said.

Players need to match five numbers and the Powerball number to win. The Powerball is played in 44 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands.
