If sales closely tracked the last large jackpot, that with an advertised annuity of \$340M, about 1%.

The powerball jackpot has rolled.  The cash value is now \$9.7M; the annuity value is \$20M.  The last two similar level drawings averaged \$13M in sales.  If the lottery sells a similar amount of tickets on this drawing, the probability for various numbers of winners is as follows:

 0 91.49% 1 8.14% 2 0.36% 3 0.01%

The powerball jackpot has rolled.  The cash value is now \$12.1M; the annuity value is \$25M.  The last \$25M jackpot had \$13.77M in sales.  If the lottery sells a similar amount of tickets on this drawing, the probability for various numbers of winners is as follows:

 0 91.01% 1 8.58% 2 0.40% 3 0.01%

A crude estimate of the long term probabilities using previous sales figures for the \$340M annuity jackpot suggests that the Powerball jackpot has a 4% chance of reaching the maximum capped jackpot and a 1% chance of rolling beyond it.    There is a 52% chance it will end up in the neighborhood of an \$90M annuity jackpot.

Yeah, Powerball's guaranteed cash jackpot for the last drawing was \$2.7 million above the actual amount of sales allocated to it. The \$5 million rollovers are Powerball's guaranteed minimum rollovers.

The powerball jackpot has rolled.  The cash value is now \$14.6M; the annuity value is \$30M.  It is reasonable to assume that the lottery will have \$13.0M in sales.  If the lottery sells this amount of tickets on this drawing, the probability for various numbers of winners is as follows:

 0 91.49% 1 8.14% 2 0.36% 3 0.01%

A crude estimate of the long term probabilities using previous sales figures for the \$340M annuity jackpot suggests that the Powerball jackpot has a 5% chance of reaching the maximum capped jackpot and a 1-2% chance of rolling beyond it.    There is a 50% chance it will end up in the neighborhood of an \$108M annuity jackpot.

I think Powerball is once again underestimating its cash jackpot. Based on sales, last night's cash jackpot should have been \$12.5 million. Sales of \$13 million for the next drawing would support a cash jackpot of \$16.4 million. My theory that Powerball funds its set prize reserve by drawing down the jackpot still holds.

I agree that something is going on and your explanation sounds reasonable.  I am no longer back calculating a sales projection from predicted jackpots, but making estimates based on previous sales.  Actually at sales levels in the low tens of millions, the jackpot rollover/winner distribution probabilities do not vary all that much.

MM is far more predictable and regular than PB these days.  I have much greater confidence in making MM projections than I do with PB.  Some of the unpredictability in PB may be a result of changed policies and some may have to do with changes in the buying public.

The powerball jackpot has rolled.  The cash value is now \$19.9M; the annuity value is \$41M.  It is reasonable to assume that the lottery will have \$14.3M in sales, comparable to the last jackpot at this level.  If the lottery sells this amount of tickets on this drawing, the probability for various numbers of winners is as follows:

 0 90.68% 1 8.87% 2 0.43% 3 0.01%

Prob988, in the PB draw on 12/31/05, I saw the guaranteed jackpot at 41 million. However, the estimated grand prize draw was 39.9 million based upon the video. Why does PB want to save money before the estimated grand prize on draw?

I'm sorry, but I don't know the answer to that question.
