In 2009, Patricia Demauro was at Atlantic City’s Borgata Hotel Casino with a friend, John Capra. Demauro first played penny slot machines but got bored after a few hours. She went to find Capra, who had been playing in the poker room. He was losing and decided to take a break to show Demauro how to play craps. She had never played the game before, but decided to try her luck.
Demauro proceeded to successfully bet 154 times in a row against rolling seven. Seven is the number that comes up the most often when throwing a pair of dice. Each of the 154 non-seven rolls of the dice meant she was winning. Big time.
According to Stanford University statistics professor Thomas Cover, the odds of Demauro’s lucky streak happening are about one in 56 trillion. Demauro finally rolled a seven after nearly four and a half hours, which ended her winning streak.
However, she walked away from the table with a sum that may have been as high as seven figures. The casino treated her to a champagne toast, a meal and a free room.
