## Roulette probability question?

The roulette wheel doesn't think "I've only delivered black results over the last 10 spins, I better increase the probability of the next result being red to even things up". If the last spin was red, the chances of the next spin being red are still Then, any time you win just bet your previous payoff previous bet plus winnings. On the other hand, if you hadn't spun the wheel to see the first red result and wanted to know the probability of seeing red over the next 2 spins and not just on the next 1 spin , the probability would be These events are mutually exclusive and exhaustive, so: Luckily, it's pretty easy to convert to either of these from a fraction. The probability of not winning any bet is.

Interesting Fact

•   There are three types of game: European; American (another order of numbers on the track, the presence of the number "00"); French (one zero, the rule of En Prison).
•  The online roulette, which is offered by online casinos, is very popular among players. The result of each spin in it is determined by a random number generator whose work can not be calculated.
•  One Englishman named Ashley Revell once sold all his possessions in order to go to Las Vegas and play roulette. This evening, Ashley won 135 thousand 300 dollars, putting everything on red.
•  English actor O'Conneri (James Bond) in January 1963 in the Italian casino "San Vincent" in three games in a row won in roulette about 30,000 dollars. All three times he put on number 17.

•  The longest game of poker in the casino is 90 hours. The record belongs to the Irishman Phil Laak. Phil not only set a record, but also won 7 thousand dollars.

## Roulette strategy probability question

The profits of two equivalent bets have the same mathematical expectation. The proofs of these statements and other important results with direct application in the creation and management of the roulette betting systems are to be found in the book, along with examples and applications.

A transformation is an act of choice over the equivalence classes of B or within a certain equivalence class. The mathematical theory of complex bets helps to restrain the area of choice and select the improved bets that fit a certain personal strategy.

Categories of improved bets: Betting on a colour and on numbers of the opposite colour This complex bet consists of a colour bet payout 1 to 1 and several straight-up bets payout 35 to 1 on numbers of the opposite colour. Let us denote by S the amount bet on each number, by cS the amount bet on the colour and by n the number of bets placed on single numbers the number of straight-up bets. S is a positive real number measurable in any currency , the coefficient c is also a positive real number and n is a non-negative natural number between 1 and 18 because there are 18 numbers of one colour.

The possible events after the spin are: A — winning the bet on colour, B — winning a bet on a number and C — not winning any bet. These events are mutually exclusive and exhaustive, so: Now let us find the probability of each event and the profit or loss in each case: The probability of not winning any bet is. The overall winning probability is. With this formula, increasing the probability of winning would be done by increasing n.

If Kahn's model is correct, redirecting the 540 million now wasted on spreading the myth of heterosexual AIDS to high-risk groups - mostly gays and inner-city drug users - could wipe out new infections entirely. french kissed. As he did this, he pulled his knob rhythmically, slowly driving himself to the edge of sexual desire and wanton lust.

The same number e. There are a number of ways to display probabilities. On the roulette charts above I have used; ratio odds, percentage odds and sometimes fractional odds. But what do they mean? This tells you the percentage of the time an event occurs.

Ratio odds X to 1. For every time X happens, the event will occur 1 time. The event occurs 1 time out of X amount of trials. As you can see, fractional odds and ratio odds are pretty similar. The main difference is that fractional odds uses the total number of spins, whereas the ratio just splits it up in to two parts.

The majority of people are most comfortable using percentage odds, as they're the most widely understood. Feel free to use whatever makes the most sense to you though of course. How to work out roulette probabilities. From my experience, the easiest way to work out probabilities in roulette is to look at the fraction of numbers for your desired probability, then convert to a percentage or ratio from there. For example, lets say you want to know the probability of the result being red on a European wheel.

With this easy-to-get fractional probability, you can then convert it to a ratio or percentage. Probabilities over a single spin. Count the amount of numbers that give you the result you want to find the probability for, then put that number over 37 the total number of possible results.

For example, the probability of: All you have to do is count the numbers that will result in a loss. Probabilities over multiple spins. Work out the fractional probability for each individual spin as above , then multiply those fractions together. For example, let's say you want to find the probability of making correct guesses on specific bet types over multiple spins: Converting probabilities in roulette.

## Shirtstorm roulette

Why it so freaking hard to drag some people into the 21st century? But no — I find, that, especially in technical contexts, I am far more likely to become impatient with my age peers. A lot of them really have become grouchy, hidebound old farts. Because the kids have little or no cred with a lot of my age peers. Even so, I spend a lot more time than seems just or right fighting inertia. Young people can be forgiven for lacking a clue.

Young means little experience, which often leads to unsound judgment. I find it wryly amusing how often both conservatives and non-conservatives who argue politics with me fail to notice this.
