The Missouri lottert will send you e-mails with the results of the game you choose and the advertised and cash jackpots.
Re: The OP,
I doubt the lottries would change the way they do it now. It sounds better for them and you have to consider that not sll payers are as informed as people here on LP. If the lottieries dropped the advertised jackpot amounts and just mentioned the cash amount there's a lot of people out there that would say something like, "Look at that Mega Millions. At least it used to start t $12 million, now they've cut that back to $7 point something million."
It would be like asking a state that has raffles with 500,000 ticket sales (using Illinois as an example) to advertise it like this:
Play our raffle. 509 winners and 499,991 losers.
(Which is exactly the way it is but they're not going to promote it that way.)
