According to Powerball’s website, there have been 1,897 drawings since the game began in 1997 with only 213 winners. That means a jackpot is only awarded 11 percent of the time. The most commonly drawn numbers in Powerball history? 32 and 41. Both have appeared 193 times, or just over 10 percent of the time. At the current odds, every number has about a 7 percent chance of appearing in any given drawing. As the game has evolved, more numbers have been added to the “Pick 5” pool to decrease the odds.
