A very lucky person has won the largest single lottery payout in 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 payment of $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.
