House edge roulette
Look at the game of Roulette. You will see that the house edge is % for the double zero game. This is how we figure the edge. In the game, there are 36 . 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.
If the ball hits your bet on the next spin, your bet is returned to you with no what winnings. In the early frontier gambling saloons, the house would set the odds on roulette tables at 27 for 1. Players at a table may bet a set amount per series or multiples of that amount. There is notably only one zero. There are different number series in roulette that have special names attached to them.
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.

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. There are 18 black numbers, which means we have 18 ways to be successful. Also, there are 18 red numbers and one green single zero, which means there are 19 ways to lose.
We have the same parents. It seems like brothers and sisters should have the same ancestry background. After all, they both got half their DNA from mom and half from dad. But because of how DNA is passed on, it is possible for two siblings to have some big differences in their ancestry at the DNA level.
So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents. Unless of course they are identical twins. This has consequences in terms of how much DNA siblings share. And even more significantly, what DNA they share. One way to think about this is to imagine DNA as a bunch of colored beads.
Since we are interested in ancestry here, we will say that different colors mean different ancestries. Imagine that a man from Japan marries a woman from Europe. Here is what this might look like:. The child might look like this:. In this case you can see that each child actually shares the same ancestry even though they got some different DNA from each parent.
It is a different story if the parents are not so red and blue. First we will add in some green beads from sub-Saharan Africa. The difference here is that mom has a small bit of African ancestry in her family tree.
This is actually pretty common in the U. As you can see, by chance the second child inherited both green beads from mom. Even though they have the same parents. It all has to do with which DNA you happen to get from each parent. And these can get passed down differently leading to different percentages. And these can be further subdivided. Now she has children with her Japanese husband. Now it is getting very confusing. Even with the same parents! Do all of this and you can see how siblings might wind up with very different ancestry results indeed.
