The roulette table is a carpet, usually green, on which all the numbers from 0 to 36 are depicted. At the top ( or left as in the photo ) we have the zero in the center, under which we have 12 rows of 3 numbers each. The numbers are placed on the table sequentially from 0 to 36, thus not reflecting the order of the numbers on the wheel.
On the sides of this large roulette number table, there are large boxes that correspond to the basic properties of the numbers described above:
Often There Are Also 3 Boxes ( Sometimes Repeated Twice ) To Represent The Dozen:
12 P representing the first dozen;
12 M representing the second dozen;
12 D representing the third dozen.
Under each column of Singapore live casino numbers there are also three empty boxes, which can be used to place a bet on the column of numbers above the empty box.
Roulette: The Calculation Of Odds. Theory And Practice.
The Purpose Of This Page Is Twofold:
on the one hand we want to provide the basic concepts of probability calculations essential for understanding the game of roulette;
on the other hand, it is also important to apply the laws of probability to roulette , with concrete examples and self-explanatory tables.
This guide therefore aims to be a sort of ” crash course in the calculation of probabilities applied to the game of roulette “. Don’t be afraid, it’s free!
Basic Concepts Of Probability
In this part we present the essential basics of probability calculation, notions that will be useful to understand some concepts that are the foundation of the probabilities applied to roulette (such as the diatribe on the fact that roulette has no memory and that extractions are truly independent. from each other).
Preamble On Events
The Events Are Events For Which You Can Ask If They Are TRUE Or FALSE:
- And 1 = an even number came up in roulette
- And 2 = the full number 15 came out in roulette
When it comes to events and probabilities, a very important logical concept is that of implication :
An event E 1 implies an event E 2 if the truth of E 2 descends from the truth of E 1 .
In other words, E 1 implies E 2 if the occurrence of the event E 1 necessarily follows the occurrence of the event E 2 .
To Give A Concrete Example:
And 1 = number 4 came out in roulette
And 2 = a black number came out in roulette
E 1 -> E 2 (reads E 1 implies E 2 )
To put it in words: the “4 came out in roulette” event implies that a black number came out in roulette, since we know for sure that the number four is in fact black.
When analyzing events and the probabilities that follow from them, it is also of fundamental importance to understand the concepts of UNION and INTERSECTION of events :
intersection of events: event that is true if both events are true and is false if at least one of them is false best live casino Singapore
the first dozen came out
the first column came out
union of events: event that is true if at least one of them is true and false if both are false
the first dozen came out
a certain column came out
Sometimes it is also very useful to reason with the denial of an event .
The denial of an event is a new event that:
it is true if the event of which it is negation is false
it is false if the event of which it is negation is true
To understand a whole series of cases, it is necessary to understand the concept of compatibility and incompatibility of events .
Two events are incompatible if the occurrence of one excludes the other.
It follows that the intersection of two incompatible events is null.
We Also Need To Define Impossible Events And Random Events :
impossible event: event that cannot occur
random event: event for which it is not possible to say whether it is true or false
An example of an impossible event is “red 4 will come out” (it is not possible because 4 is by definition black).
An example of a random event: “throwing the ball will come out on 7”.
