This is NOT homework. Neither is this gambling. This is just an mathematical physical exercise in probability.

Irrelevant or non-meaningful answers will be reported.

Hypothetical scenario:

A hypothetical Las Vegas casino, “The Illusion”, introduces a new game known as “Lucky # 13″. In this game, each and every player plays independently of other players against a single dealer.

The dealer throws his single red die very first and notes down (and paperwork) the worth of his very first roll. (This is like the dealer’s “up card” in blackjack.)

Each successive player will then consider the single WHITE player die and roll as long as he wants. His objective is to surpass the dealers last total. If the player’s total exceeds “13″, he busts! At that point, the dealer collects this player’s bet (and any side-bets) and the turn goes to the up coming player.

Right after all the gamers have played their turn, the dealer rolls his red die once more. He adds this roll to the very first roll and continues to roll until finally his complete is amongst “ten” to “13″, i.e, 10 ,eleven, 12 or 13. If the dealer busts, all gamers still energetic gets paid $ 1 for every $ one bet PLUS their authentic bet is returned.

If the dealer finishes with ten-13, the dealer’s total is compared to the player’s. And every single player’s bet is resolved.

___

I have carried out the calculations, so I have a clear idea of the solutions. Even so, my approach and calculations could be wrong.

For the following concerns, you do NOT have to provide actual data. Just make positive your method is based on actual calculations. If you DO give data, and the strategy and data are correct, the first right 1 will automatically get “Finest Answer”.

Question # 1: If the dealer is essential to halt at totals ten-13, what is the player’s optimum strategy? What is the player’s mathematical expectation?

Query # 2: If the dealer is necessary to quit at totals 11-13, what is the player’s optimum strategy? What is the player’s mathematical expectation?

Question # 3: If there is a “side bet” where the house pays for player-dealer ties (except when the player busts — in which situation, the player loses), how a lot would the casino have to spend players for the bet to be fair? 4x (4x PLUS return of original bet)? 5x (5x PLUS return of original bet)?

Query # 4: Believe about this: with the expected worth of two rolls equal to 7 if the dealer has a first roll of “6″, then he is probable to have “13″ as his last total. Really should the player alter his approach primarily based on the “conditional probability” of dealer’s first roll?

Thanks!
