A video poker machine at ABC casino randomly deals you 5 cards at the rate of 55 hands a minute, and will pay out $200 for any 4 of a kind, $600 for any straight flush (non-royal), and $3000 for a royal flush.
You can play this game for a yet to be determined amount that will give you exactly 15 minutes of play (825 total hands). In intervals of $1 ($10,$11,$12,etc), what is the absolute lowest amount you can play this game for that still has an edge to the house?
To get the proper answer, you can try and do the math, you can take a wild stab, or you can look to the former stars of Las Vegas and the twinkling stars in China to get the answer.
I'll reveal the answer in a few days.
Good Luck.
