Blues Brothers

The Blues Brothers are an American blues and soul revivalist band founded in 1978 by comedians Dan Aykroyd and John Belushi as part of a musical sketch on Saturday Night Live. Belushi and Aykroyd, respectively in character as lead vocalist "Joliet" Jake Blues and harpist/vocalist Elwood Blues, fronted the band, which was composed of well-known and respected musicians. The band made its debut as the musical guest on the April 22, 1978, episode of Saturday Night Live. The band then began to take on a life beyond the confines of the television screen, releasing an album, Briefcase Full of Blues, in 1978, and then having a Hollywood film, The Blues Brothers, created around its characters in 1980. After the death of Belushi in 1982, the Blues Brothers have continued to perform with a rotation of guest singers and other band members. The original band reformed in 1988 for a world tour and again in 1998 for a sequel to the film, Blues Brothers 2000. They make regular appearances at musical festivals worldwide.

Problem Gambling

People sometimes call problem gambling ludomania. Problem gambling is an urge to gamble despite harmful negative consequences or personal desire to stop. Problem gambling often means that the gambler hurts other people. Severe problem gambling is clinical pathological gambling if the gambler meets certain criteria. Although the term gambling addiction is common in the recovery movement, pathological gambling is an impulse control disorder and is therefore not an addiction according to the American Psychological Association.

A study by the United Kingdom Gambling Commission, called the British Gambling Prevalence Survey 2007, found that approximately 0.6% of the adult population had problem gambling issues, the same percentage as in 1999. The highest prevalence of problem gambling is amongst those who participated in spread betting 14.7%, fixed odds betting terminals 11.2% and betting exchanges 9.8%.

Research by governments in Australia led to a universal definition of problem gambling, which appears to be the only research based definition not to use diagnostic criteria. Problem gambling involves many difficulties in limiting money and/or time spent on gambling which leads to adverse consequences for the gambler, others or for the community. Most other definitions of problem gambling can usually be simplified to any gambling that causes harm to the gambler or someone else in any way. However, these definitions are usually coupled with descriptions of the type of harm or the use of diagnostic criteria. According to DSM-IV, pathological gambling is separate from a manic episode. When the gambling occurs independent of other impulsive, mood or thought disorders is becomes its own diagnosis.

Available research seems to indicate that problem gambling is an internal tendency and that problem gamblers will tend to risk money on whatever game may be available, rather than a particular game being available. However, research also indicates that problem gamblers tend to risk money on fast paced games. A problem gambler is much more likely to lose a lot of money on roulette or slot machines, where rounds end quickly and there is a constant temptation to play again or increase bets, as opposed to a state lottery where the gambler must wait until the next drawing to see results.

Most treatment for problem gambling involves counseling, programs with steps to recover, self help, peer support, medication or a combination of these. However, no one treatment is most efficacious and the United States Food and Drug Administration has not approved medications for the treatment of pathological gambling.

Cognitive behavioral therapy helps reduce symptoms and urges related to gambling. This type of therapy focuses on the identification of the thought processes, mood and cognitive distortions that increase the vulnerability of the gambler. Additionally, cognitive behavioral therapy approaches frequently utilize techniques that build skills geared toward relapse prevention and assertiveness.

The odds in favor of an event or a proposition are expressed as the ratio of a pair of integers, which is the ratio of the probability that an event will happen to the probability that it will not happen. For example, the odds that a randomly chosen day of the week is a Sunday are one to six, which is sometimes written 1:6, or 1/6. In probability theory and statistics, where the variable p is the probability in favor of the event, and the probability against the event is therefore 1-p, the odds of the event are the quotient of the two, or p/(1-p). That value may be regarded as the relative likelihood the event will happen, expressed as a fraction if it is less than 1, or a multiple if it is equal to or greater than one of the likelihood that the event will not happen. In the example just given, saying the odds of a Sunday are one to six or, less commonly, one-sixth means the probability of picking a Sunday randomly is one-sixth the probability of not picking a Sunday. While the mathematical probability of an event has a value in the range from zero to one, the odds in favor of that same event lie between zero and infinity. The odds against the event with probability given as p are (1-p)/p.

The odds against Sunday are 6:1 or 6/1 = 6: it is 6 times as likely that a random day is not a Sunday. Hence 'odds' are an expression of relative probabilities. Generally 'odds' are quoted in this format odds against rather than as odds in favor of, because of the possibility of confusion of the latter with the fractional probability of an event occurring. E.g., the probability of a random day of the week is a Sunday is 'one-seventh' 1/7. A bookmaker may for his own purposes use 'odds' of 'one-sixth', but the overwhelming everyday use by most people is odds of the form 6 to 1, 6-1, 6:1, or 6/1 all read as 'six-to-one' where the first figure represents the number of ways of failing to achieve the outcome and the second figure is the number of ways of achieving a favorable outcome: thus these are odds against. In other words, an event with m to n odds against would have probability n/ m + n, while an event with m to n odds on would have probability m/ m + n. Even in probability theory, odds may be more natural or more convenient than probabilities. This is in particular the case in problems of sequential decision making as for instance in problems of how to stop online on a last specific event, which is solved by the odds algorithm.

In some games of chance, using odds against is also the most convenient way to understand what winnings will be paid if the selection is successful: the winner will be paid 'six' of whatever stake unit was bet for each 'one' of the stake unit wagered. For example, a winning bet of 10 at 6/1 will win '6 × 10 = 60' with the original 10 stake also being returned. Betting odds are skewed to ensure that the bookmaker makes a profit—if true odds were offered the bookmaker would break even in the long run—so the numbers do not represent the true odds.

Odds on means that the event is more likely to happen than not. This is sometimes expressed with the smaller number first 1:2 but more often using the word on 2:1 on meaning that the event is twice as likely to happen as not.

Decimal presentation

Taking an event with a 1 in 5 probability of occurring i.e. a probability of 1/5, 0.2 or 20%, then the odds are 0.2 / 1 − 0.2 = 0.2 / 0.8 = 0.25. This figure 0.25 represents the monetary stake necessary for a person to gain one monetary unit on a successful wager when offered fair odds. This may be scaled up by any convenient factor to give whole number values. For example, if a stake of 0.25 wins 1 unit, then scaling by a factor of four means a stake of 1 wins 4 units.

Ratio presentation

Fixed odds gambling tends to represent the probability as fractional odds, and excludes the stake. For example, 0.20 is represented as 4 to 1 against written as 4-1, 4:1, or 4/1, since there are five outcomes of which four are unsuccessful. Thus, the stake returned must be added to the odds to compute the entire return of a successful bet. In craps, the payout would be represented as 5 for 1, and in money line odds as +400 representing the gain from a 100 stake.

By contrast, for an event with a 4 in 5 probability of occurring i.e. a probability of 4/5, 0.8 or 80%, then the odds are 0.8 / 1 − 0.8 = 4. If one bets 4 units at these odds and the event occurs, one receives back 1 unit plus the original unit 4 units stake. This would be presented in fractional odds of 4 to 1 on'' written as 1/4 or 1–4 , in decimal odds as 1.25 to include the returned stake, in craps as 5 for 4, and in money line odds as −400 representing the stake necessary to gain 100.

Fixed odds are not necessarily presented in the lowest possible terms; if there is a pattern of odds of 5–4, 7–4 and so on, odds which are mathematically 3–2 are more easily compared if expressed in the mathematically equivalent form 6–4. Similarly, 10–3 may be stated as 100–30.

Gambling odds versus probabilities

In gambling, the odds on display do not represent the true chances that the event will occur, but are the amounts that the bookmaker will pay out on winning bets. In formulating his odds to display the bookmaker will have included a profit margin which effectively means that the payout to a successful bettor is less than that represented by the true chance of the event occurring. This profit is known as the 'over-round' on the 'book' the 'book' refers to the old-fashioned ledger in which wagers were recorded, and is the derivation of the term 'bookmaker' and relates to the sum of the 'odds' in the following way:

In a 3-horse race, for example, the true probabilities of each of the horses winning based on their relative abilities may be 50%, 40% and 10%. These are simply the bookmaker's 'odds' multiplied by 100% for convenience. The total of these three percentages is 100%, thus representing a fair 'book'. The true odds against winning for each of the three horses are 1-1, 3-2 and 9-1 respectively. In order to generate a profit on the wagers accepted by the bookmaker he may decide to increase the values to 60%, 50% and 20% for the three horses, representing odds against of 4-6, 1-1 and 4-1. These values now total 130%, meaning that the book has an over round of 30 130 − 100. This value of 30 represents the amount of profit for the bookmaker if he accepts bets in the correct proportions on each of the horses. The art of bookmaking is that he will take in, for example, $130 in wagers and only pay $100 back including stakes no matter which horse wins.

Profiting in gambling involves predicting the relationship of the true probabilities to the payout odds. Sports information services are often used by professional and semi-professional sports bettors to help achieve this goal.

The odds or amounts the bookmaker will pay are determined by the total amount that has been bet on all of the possible events. They reflect the balance of wagers on either side of the event, and include the deduction of a bookmaker’s brokerage fee vig or vigorish.

Indian Poker

Blind man's bluff also called Indian poker, or squaw poker or Indian head is a version of poker that is unconventional in that each person sees the cards of all players except his own.

The standard version is simply high card wins. Each player is dealt one card that he displays to all other players traditionally stuck to the forehead facing outwards- supposedly like an Indian feather. This is followed by a round of betting. Players attempt to guess if they have the highest card based on the distribution of visible cards and how other players are betting.

Other versions forehead stud are variations on stud poker, in which one or more of the hole cards is hidden from its owner, but shown to all other players, as above. During its coverage of the 2004 World Series of Poker, ESPN showed a Blind Man's Bluff version of Texas hold'em.
