+1 for pointing out that it is actually a $491MM payout that you can choose to take as a $800MM annuity over 20(?) years.<p>You also have to subtract taxes from the payout, which also eats into the payout. I would expect it would be 30% or higher, depending on how much you spend on a tax lawyer (which, of course, cuts into the payout as well).<p>The only[1] way to win is to not play.<p>[1] Odds are 292,201,338 to 1 of winning by not playing.
