Overround
In gambling parlance, making a book is the practice of laying bets on the various possible outcomes of a single event. The phrase originates from the practice of recording such wagers in a hard-bound ledger (the 'book') and gives the English language the term bookmaker for the person laying the bets and thus 'making the book'. Sidney 2003, pp. 13, 36 Making a 'book' (and the notion of overround) A bookmaker strives to accept bets on the outcome of an event in the right proportions in order to make a profit regardless of which outcome prevails. See Dutch book and coherence (philosophical gambling strategy). This is achieved primarily by adjusting what are determined to be the true odds of the various outcomes of an event in a downward fashion (i.e. the bookmaker will pay out using his actual odds, an amount which is less than the true odds would have paid, thus ensuring a profit). The odds quoted for a particular event may be fixed but are more likely to fluctuate in or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vigorish
Vigorish (also known as ''juice'', ''under-juice'', the ''cut'', the ''take'', the ''margin'', the ''house edge'' or simply the ''vig'') is the fee charged by a bookmaker (or ''bookie'') for accepting a gambler's wager. In American English, it can also refer to the interest owed a loanshark in consideration for credit. The term came to English usage via Yiddish slang ( yi, וויגריש, translit=vigrish, translit-std=ISO, italic=unset), which was itself a loanword from Ukrainian ( uk, ви́граш, translit=výhraš, translit-std=ISO, lit= winnings, profit, italic=unset) or Russian (russian: вы́игрыш, translit=výigryš, translit-std=ISO, lit=gain, winnings, italic=unset). As a business practice it is an example of risk management; by doing so bookmakers can guarantee turning a profit regardless of the underlying event's outcome. As a rule, bookmakers do not want to have a financial interest creating a preference for one result over another in any given sporting ev ...

Odds
Odds provide a measure of the likelihood of a particular outcome. They are calculated as the ratio of the number of events that produce that outcome to the number that do not. Odds are commonly used in gambling and statistics. Odds also have a simple relation with probability: the odds of an outcome are the ratio of the probability that the outcome occurs to the probability that the outcome does not occur. In mathematical terms, where p is the probability of the outcome: :\text = \frac where 1-p is the probability that the outcome does not occur. Odds can be demonstrated by examining rolling a six-sided die. The odds of rolling a 6 is 1:5. This is because there is 1 event (rolling a 6) that produces the specified outcome of "rolling a 6", and 5 events that do not (rolling a 1,2,3,4 or 5). The odds of rolling either a 5 or 6 is 2:4. This is because there are 2 events (rolling a 5 or 6) that produce the specified outcome of "rolling either a 5 or 6", and 4 events that do n ...

Full Cover Bet
A full cover bet is any bet which consists of all available multiple bets over a given number of selections. Examples of full cover bets: * '' Trixie'' - three selections * ''Yankee'' - four selections * '' Canadian or Super Yankee'' - five selections * '' Heinz'' - six selections * '' Super Heinz'' - seven selections * ''Goliath'' - eight selections Examples of full cover bets with singles included: * ''Patent'' - three selections * '' Lucky 15'' - four selections * '' Lucky 31'' - five selections * '' Lucky 63'' - six selections The ''Lucky'' bets are so named because of the bookmaker's practice of offering bonuses for one or more winning selections; most common of which is 'double the odds' for one winner. The offering of a percentage increase in winnings for the success of two or more selections in these ''Lucky'' bets is primarily to compensate for the compounding of the overround when two or more events with individual overrounds on their books are combined in doubles, tre ...

Betting Exchange
A betting exchange is a marketplace for customers to bet on the outcome of discrete events. Betting exchanges offer the same opportunities to bet as a bookmaker with a few differences. Gamblers can buy (also known as "back") and sell (also known as "lay") the outcome, and they can trade in real-time throughout the event, either to cut their losses or lock in profit. Bookmaker operators generate revenue by offering less efficient odds. Betting exchanges normally generate revenue by charging a small commission on winning bets. History The first betting exchanges were Matchbook, flutter.com and Betfair. Flutter and Betfair merged in 2001 with Betfair chosen as the primary betting exchange. The flutter.com site ceased operations in January 2002. Since then Betfair has maintained a leading position in the betting exchange market. BETDAQ (which also traded as the 'Ladbrokes Exchange') is believed to be the second largest betting exchange and it had an estimated 7% share of the bettin ...

Bookmaker
A bookmaker, bookie, or turf accountant is an organization or a person that accepts and pays off bets on sporting and other events at agreed-upon odds. History The first bookmaker, Ogden, stood at Newmarket in 1795. Range of events Bookmakers in many countries focus on accepting bets on professional sports, especially horse racing and association football or Indian Premier League cricket. However, a wider range of bets, including on political elections, awards ceremonies such as the Oscars, and novelty bets are accepted by bookmakers in some countries. Operational procedures By "adjusting the odds" in their favour (paying out amounts using odds that are less than what they determined to be the true odds) or by having a point spread, bookmakers aim to guarantee a profit by achieving a 'balanced book', either by getting an equal number of bets for each possible outcome or (when they are offering odds) by getting the amounts wagered on each outcome to reflect the odds.

Mathematics Magazine
''Mathematics Magazine'' is a refereed bimonthly publication of the Mathematical Association of America. Its intended audience is teachers of collegiate mathematics, especially at the junior/senior level, and their students. It is explicitly a journal of mathematics rather than pedagogy. Rather than articles in the terse "theorem-proof" style of research journals, it seeks articles which provide a context for the mathematics they deliver, with examples, applications, illustrations, and historical background. Paid circulation in 2008 was 9,500 and total circulation was 10,000. ''Mathematics Magazine'' is a continuation of ''Mathematics News Letter'' (1926-1934) and ''National Mathematics Magazine'' (1934-1945.) Doris Schattschneider became the first female editor of ''Mathematics Magazine'' in 1981. .. The MAA gives the Carl B. Allendoerfer Awards annually "for articles of expository excellence" published in ''Mathematics Magazine''. See also *''American Mathematical Mont ...
