Strong sales boosted a Powerball jackpot to an estimated $1.6 billion, making it the largest lottery prize in history. A drawing will be held Saturday night for the Powerball prize, which hasn’t been won in more than three months. That string of 39 consecutive drawings without a winner is a reflection of the tough odds of winning a jackpot, at 1 in 292.2 million. The jackpot increased Friday is the prize for a winner who chooses an annuity, paid annually over 29 years. Almost all winners instead opt for the cash prize, which for Saturday night’s drawing would be an estimated $782.4 million.
