Strategy I Hit when the sum of the first two cards is less than the dealer’s upcard
Let x be the player’s sum of card values of the first two cards.
Let D be the dealer’s upcard(the second card).
If x < D, the player should always hit.
When x < D, it is obvious that x must be less than the dealer’s final value (covered card + upcard), given that the sum of the first two cards of the dealer is[pic] no busting. Therefore, under this situation, the player must hit. Otherwise, his probability of winning is 0.
Strategy II Hit or Stand
If the hard total is 11 or less, the player should always hit. This is because no matter what card the player is getting, the total hand value will not exceed 21. By using the Hit ot Stand strategy, the house edge can be cut to as low as 2%.[1] Fig. 1 is the decision making chart when using this strategy.

Mathematics: Probability
3333 Words  14 PagesIntroduction The word Probability derives from probity, a measure of the authority of a witness in a legal case in Europe, and often correlated with the witness 's nobility. In a sense, this differs much from the modern meaning of probability, which, in contrast, is used as a measure of the weight of empirical evidence, and is arrived at from inductive reasoning and statistical inference. A short history of Probability Theory............ The branch of mathematics known as probability theory was inspired…

The 'But for' Test and 'Balance of Probabilities' Essay
1712 Words  7 PagesThe ‘but for’ test and ‘balance of probabilities’ are used to determine whether the negligent act was the cause of injury. The ‘but for’ test is ideal for cases like Barnett where ‘but for’ the negligence of the doctor the claimant would have died because of the irreversible implications of ingesting arsenic. More complex cases require the ‘balance of probabilities’ to illustrate the chance of recovery and the diminished prospects as demonstrated in Wilsher where the injury could have been sustained…

Questions on Probability
260 Words  1 Pages1. A card is drawn at random from a standard 52card deck. Find the probability that the card is not a queen. 52 card 4 queens = 48 cards that are not queens. 48/52 = 12/13 or 0.923 = 92.3% probability of not drawing a queen from a standard 52card deck. 2. Two fair dice are rolled. Find the probability that the sum of the two numbers is not greater than 5. 1+1, 1+2, 1+3, 1+4, 2+1, 2+2, 2+3, 3+1, 3+2, 4+1 are the 10 possible occurrences of two fair dice rolling numbers not greater than 5. With…

Factors Responsible for the Probability of Divorce
1009 Words  4 PagesProbability of Divorce: Contrary to the reality in western industrialized nations, there is a common assumption that longer lifespans contribute to longer marriages. As the average length of marriage remains significantly the same, the reason for the end of marriage has changed from death to divorce. Actually, it's currently estimated that half of marriages in the United States will end either in separation or divorce before the 20th wedding anniversaries of the couples. The other half of these…

Probability Concepts
893 Words  4 PagesProbability Concepts Introduction Probability concepts describe how uncertainty can be quantified, and it measures the possibility or impossibility of occurrence of a given event. Probability is the chance of a particular outcome, out of a number of times possible outcomes occurring for a certain event. These concepts help in making inferences about situations and to quantify the uncertainty of future events. It is, therefore, useful to review basic concepts and laws of probability to understand…
