Keno, as you know, is a gambling game where your winning depends not just on luck but also on your knowledge of Keno math. The game basically involves a computer choosing 20 numbers from a set of 80, and the gambling bit involves you betting on which are the 20 numbers the computer is likely to choose.
As you can see, while there is basically no skillset involved in the game of Keno, for after all it is just about the computer choosing 20 random numbers out of 80, knowing your Keno math would certainly be a big help. By applying math in Keno, you would be able to work out the odds involved with betting against the different numbers and then place your wager accordingly.
There are a couple of things you would realize once you did your Keno math. First of all, just because the game involves a lot of luck and minimal skill does not automatically translate to you winning easily. In fact, you’ll see that the house advantage that the casino enjoys in Keno is way more than what you see in many of the other casino games – between 4% and 30%.
Even with basic knowledge of math, it is not very hard to work out the odds of the different numbers being chosen to make up the final list of 20 that the computer will generate. A good way of calculating the odds is to use the theory of probability.
Using the theory of probability, you can see that a number has a one-in-four chance of being picked to make the list of 20 numbers. However, as the count increases, the chances of numbers getting on that list grow thinner. The chances of you guessing two of the numbers correctly goes up, from one-in-four for one number to 1-in-16.
Add to this the number of variables that would come into play as the numbers increase and you can see why the chances of guessing the correct number grow slimmer. If you do your math right, you will find out that the chances of guessing 10 of the 20 numbers correctly are a whopping 1-in-253,801, while the chances of guessing all the 20 numbers correctly are a mind-boggling 1-in-3, 535, 316, 142, 212, 180, 000.
In the face of such stupendous odds, how would you go about calculating the odds of getting the numbers right using mathematics in Keno? One way of doing this would be to use the Combine Function, which helps you find out the different ways in which a set of numbers can be drawn from an entire set.
One of the good things that come out of having such steep odds is that when someone does get the maximum numbers right, the winnings are almost always huge.
