The book describes the exploits of a group of University of California Santa Cruz students, who called themselves the Eudaemons , who in the late s used computers in their shoes to win at roulette.

Roulette is a casino game named after the French word meaning little wheel. In the game, players may choose to place bets on either a single number, various groupings of numbers, the colors red or black, whether the number is odd or even, or if the numbers are high 19—36 or low 1— To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the outer edge of the wheel.
The first form of roulette was devised in 18th century France. Many historians believe Blaise Pascal introduced a primitive form of roulette in the 17th century in his search for a perpetual motion machine.
The game has been played in its present form since as early as in Paris. An early description of the roulette game in its current form is found in a French novel La Roulette, ou le Jour by Jaques Lablee, which describes a roulette wheel in the Palais Royal in Paris in The description included the house pockets, "There are exactly two slots reserved for the bank, whence it derives its sole mathematical advantage.
The book was published in The roulette wheels used in the casinos of Paris in the late s had red for the single zero and black for the double zero. To avoid confusion, the color green was selected for the zeros in roulette wheels starting in the s. In some forms of early American roulette wheels, there were numbers 1 through 28, plus a single zero, a double zero, and an American Eagle.

The house edge also known as house take, or house advantage is the major source of income for casinos. In fact, establishments such as these have predetermined payout odds for every table game they offer in order to score profit from each bet placed by their visitors. As we already pointed out, players are able to choose from a variety of bets at the roulette table.
With that many betting options available, there are people who doubt that the advantage of the house remains one and the same. Therefore, people with little or no knowledge of roulette may require a more profound understanding of the way the house edge is estimated.
Let us use the French roulette wheel as an example again. Despite that the wheel offers 37 possible winning numbers, a player will receive a payout of 35 to 1 for a bet on a single number. If we multiply the house edge by the probability of success and present the result as a percentage, we will come to the following:.
Another way to come to this result is to multiply the difference between the actual odds for a loss and the house odds by the probability of success:. If we use these numbers in the House Edge formula above, we will come to the following:. The same is valid for other inside bets. Let us take corner bets four numbers , for example. In order to place these numbers into the formula above and be able to subtract fractions, we need equal denominators.
This way we will come to the following:. As we can see, the edge of the house for a corner bet is exactly the same as that for a straight-up bet. Someone may ask what the case with even-money outside bets will be. Let us bet 1 unit on black.
In education rhetoric, there are two common narratives regarding parents and teachers. The most important thing I can do is to read to my children every night, to not have them watching TV and to really be a partner with that teacher. Parents have to step up. Clearly, parents and teachers would prefer to live in the world of the second narrative, where parents and teachers work together for the wellbeing of children everywhere.
Hess, director of education-policy studies at the American Enterprise Institute, believes that responsible parents — the type that readily partner with teachers — are often slighted by the modern educational system.
Hess uses two critical examples to advance his argument that the current educational system penalizes the responsible parents. First, Hess breaks down college financial aid. Responsible parents help their children save whatever they can to go to college or university. However, under current financial aid policies, students who have saved any money at all for college are entitled to less assistance, even if the parents are unable to contribute beyond the existing savings.
Hess contends that this situation will ultimately make it more difficult for children of responsible parents to succeed in college or university. The second scenario Hess examines relates to elementary education. In practice, differentiated education often means that children of responsible parents receive less educational attention than their less well-prepared peers.
Less-prepared students often receive extensive one-on-one attention from teachers and support staff. Hess believes that the solution to this issue lies within the established partnership between parents and teachers.
