Re: Probability of no one hitting the Powerball tonight?
It appears the jackpot has gone from $300MM to $340MM, which (using an annuity factor of 2) would be a cash increase of $20MM. From each ticket sold, $.30 goes to the jackpot -- so the outstanding tickets for this draw is estimated to be $20MM/$.30, or about 66,666,666. The odds of a winner are 1:146MM.
