A very lucky person has won the largest single lottery payoutin United States history - $758.7 million.A 53-year-old hospital worker from Massachusetts, Mavis Wanczyk,came forward Thursday to claim her prize in the Powerball drawing.She said she had quit her job and wanted to take some time to relax.Lottery officials say she chose to take a single paymentof $480 million, or $336 million after taxes.Winners can also choose to receive the jackpot in 30 payments over 29 years.The winning numbers were drawn Wednesday night in the Powerball,which is played in most U.S. states.The matching numbers were 6, 7, 16, 23 and 26,with the Powerball number 4.Wanczyk bought her ticket Wednesday at a store in a small Massachusetts town.She said for some of the winning numbers, she chose birthdays of people she knows.The jackpot was the second-largest overall lottery prize in U.S. history.The biggest jackpot ever was a $1.6 billion Powerball payout in 2016.But that prize was shared among three winners.Lottery officials reported the odds of winning Wednesday's Powerballwere one in 292.2 million.The Powerball lottery is held twice a week, with numbers drawn from two containers.One container holds 69 numbered balls, from which five are drawn.Another ball – known as the Powerball - is selected from the other container.To win the full jackpot, a person must match all six numbers.The jackpot continues to grow each time there is no top prize winner.The last time someone matched all six Powerball numbers was June 10,when a California man won $447.8 million.The jackpots have been growing larger because there are fewer big winners.This is because lottery officials have made changes to the gamethat make the odds of winning more difficult, The Washington Post reports.Two years ago, the chances of winning were about 1 in 175 million.This compares to the latest drawing's odds of one in 292.2 million.This resulted from a change to the game in October 2015, when Powerball increased the number of ballsfrom 59 to 69, according to the newspaper.Experts say the bigger the jackpot gets,the amount of media coverage also increases,driving ticket sales higher and higher.Several studies have shown that lower-income Americansbuy most of the lottery tickets.But the huge lottery payoffs do not only benefit the winners.U.S. states participating in lotteries also get a percentage of revenue,amounting to hundreds of millions of dollars.Some states put the lottery earnings in a general state fund,which can be used for many things.But many others set the money aside for specific purposes- such as education, environmental programs or anti-crime efforts.Some states even earn more money from the lotterythan from income taxes on companies, according to Reuters news agency.
