SACRAMENTO, Calif—A group of California co-workers who decided to play the lottery on a whim won last month’s $543 million Mega Millions jackpot, the largest prize ever on a single state ticket, the California Lottery said Friday.
The 11 co-workers who work in the financial industry in the San Francisco Bay Area said they don’t have a regular lottery pool but decided to chip in $2 a piece when they heard how big the jackpot had become, the Lottery said in a news release Friday.
