There are many games based on luck, like slots machines, craps and roulette. As we are sure you know Keno is one gambling game that includes winning based on more than just luck, exactly like video poker. It also includes Keno math. This game revolves around a computer that chooses twenty numbers out of eighty and we are faced with the gambling part put into betting on what 20 numbers the given computer might end up choosing.

Even if it seems that no skills are needed in Keno due to the fact that 20 random numbers are chosen we still need to know Keno math because it can help us out a lot. By using math in Keno a player can calculate odds with betting against some numbers and make proper wagers.

Some things need to be understood when thinking about Keno math. First we have to understand that this game includes much luck and only minimal skill. This does not mean that anyone can just win or lose. In fact, the advantage that the house has is quite bigger than a lot of other common casino games. The edge is somewhere between 4 percent and 30 percent.

Even with just basic math knowledge we can work out odds for different numbers so that the list of twenty is a little bit clearer. Probability theory stands out as a very good way to calculate odds.

By using probability theory we can see that one number has 1 chance in 4 that it will be picked to form the 20 numbers list. However, as we see the count increasing chances that more numbers will reach our list become lower. Chances that you guess 2 numbers correctly go up from 1 chance in 4 to 1 chance in 16.

If we add variable numbers that are to come in play when numbers increase then we can clearly see why guess correct numbers chances grow constantly slimmer. If we are doing our math right we can see that the chance to guess 10 numbers of all 20 is just 1 to 253,801. To make everything even more interesting, the chance that you guess all of the winning 20 numbers is huge and we are talking about a chance of 1 to more than 3,500,000,000,000,000,000.

Since we are in front of such odds how can we calculate the correct odds that we are to guess numbers correctly in Keno? We can do this if we use Combine Function, which can help us find out different ways to draw a set of given numbers out of a whole set of numbers.

The one part of Keno that is attractive is that although there are very steep odds this also means that if you do get all the numbers right you are to be faced with a huge win.
