The Powerball drawing that will start on Saturday, Sept. 6, at 10:59 p.m. ET will be for a massive $1.8 billion jackpot, making it the second-largest lottery jackpot in the history of the United States.

People across the country will be flocking to buy Powerball tickets at gas stations and convenience stores on Saturday, but the chances of winning are astonishingly low − about 1 in 292 million, the lottery association said. By comparison, about 342 million live in the United States, according to the Census Bureau.
