Roulette Odds

Of course four outcomes of the number 9 in a row are not easy to come by, that is 9,9,9,9. Even though the sequential probability of four 9s appearing in a sequence is quite high, it is of (1 to 38 x 1 to 38 x 1 to 38 x 1 to 38 = 1 to 2,085,136), the absolute probability of it appearing at the specific spins is at all times 1 out of 38 as for the double roulette wheel.

Since the sequence of the same four numbers is hard to come by, then it follows that a chain of any other four numbers is also rare such as 64 24 10 52 or 42 16 70 26. The reason for this is because a chain of four 9s is easier to take note of than say 42 16 70 26. Therefore if you are yet to see a chain of four successive 9s, chances are that you have as well not seen a coherence of 42 16 70 26 or 64 24 10 52.

This essentially means that getting five consecutive same digits such as 9 9 9 9 is just as hard as it is to get 9 9 X where X represents any number from the Roulette wheel. What this means is that merging absolute probability and sequential does not always have the effect of giving you an advantage.

Let's make an assumption!

To get a clearer picture, let us assume that you decide to have nine kids and your wife agree to that too. Let's also assume that the quantity of boys equals to the quantity of girls and there is absolutely no genetic disposition whatsoever simply for illustration purposes. If you want to have all boys, what odds do you have of getting all nine boys? This is what is called sequential probability.

On the other hand if you already have eight boys and you are expecting the ninth kid, what odds do you have of getting the ninth kid a boy? You are now looking at absolute probability.
