“The lotteries association estimates that 65% of revenue from ticket sales goes into the prize pool, and 24% is used for state initiatives.
The cash option
The cash option is based on what the lottery has in its prize pool on the day of the draw. For the $1.326 billion Powerball jackpot, the cash option was $621 million, which is a little less than half the jackpot.”
也就是說：$1.22B Mega Millions lottery，如果選擇拿現金，隻能拿到$571M。 而買彩票的總銷售額是 $571M / 65% = $879M
