Hello all,

I'm attempting to figure out if I can create a formula to:

1) Calculate the probability of the next number being either Odd, Even, or Same.

2) Calculate the probability of the next number being either Higher, Lower, or Same?

> From the below table of numbers (newest numbers are at the top - oldest to the bottom):

> [The next number in the sequence was a 7 - IE. 7 6 1 2 7 7 etc.]

6
1
2
7
7
0
7
3
8
5
2
3
8
5
1
0
7
9
1
6
5
6
2

AND

3) Is there a way to calculate the probability of which catagory the next number may come from?

I use low, medium, high for these numbers.

Low being 0, 1, 2, 3

Medium being 4, 5, 6

High being 7, 8, 9

Does anyone know how to do these types of formulas? Thanks ahead of time for any suggestions.

Based on the short term it would be easy to total each category and divide by the number of draws.

Random being, well, random, gives you only a 10% chance of any number in a given position.

However, a number going higher or lower, or staying the same, depends on the number. If the number is 7, then you have a 70% chance (0,1,2,3,4,5,6) it will go low, a 10% chance (7) it remains the same and a 20% chance (8,9) that it will go higher.

Depending on the number of draws, the biggest drawback is the 'bulge' on the low digit totals. This is Texas Evening:

The reason you have a disparity is 40% of the total is designated as Low, (0,1,2,3) versus 4,5,6 and 7,8,9.

Might be an interesting idea to see how the other categories do as well.

Good Luck!

Evening garyo1954,

Sorry not to have gotten back sooner...

Below is my Texas Pick 3 Day game. According to my records, it has 1325 games in it since the last matrix changed on Nov. 12, 2007.

 TOTAL DRAWS - COLUMN COUNT - NUMBER FREQUENCY and PERCENTAGE CHART Column Counts 0 1 2 3 4 5 6 7 8 9 1st Column Count Number Frequency 140 134 111 120 144 145 139 112 151 129 Percentage for 1st Column Count 10.57% 10.11% 8.38% 9.06% 10.87% 10.94% 10.49% 8.45% 11.40% 9.74% 2nd Column Count Number Frequency 136 115 135 124 144 133 119 121 138 160 Percentage for 2nd Column Count 10.26% 8.68% 10.19% 9.36% 10.87% 10.04% 8.98% 9.13% 10.42% 12.08% 3rd Column Count Number Frequency 134 153 130 140 143 110 120 137 129 129 Percentage for 3rd Column Count 10.11% 11.55% 9.81% 10.57% 10.79% 8.30% 9.06% 10.34% 9.74% 9.74%

According to my table, in the 1st column, the number 8 has hit the most times. In the 2nd column, the number 9 has hit the most. And in the 3rd column, the number 1 is the winner. Playing the "most hits" (8 9 1) doesn't work. That's why I'm looking for another why to analyze the numbers...

Based on the above table, I can see which number has hit the most times in which position. I was attempting to figure out how to use the "probability" functions to see if a different number popped to the surface other than what is apparent in the table. As for the 10% figure verses the 40% figure, if I understand correctly, each number has a 10% chance of being drawn (random). As to the L, M, H - it's just the catagories I placed the numbers into. I find it easier to grasp this way when I'm looking at the "historical table" draws.

Is there a formula that provides the type of info I'm looking for OR would it be some sort of VBA script?

By the way, which program are you using that provides a printout like you've shown?

Thanks very much for the reply.

Thanks very much for the reply.

The people who have studied gambling theory would be better suited to answer the formula question. In my opinion, the formula you are looking for depends on how you see the lottery drawings.

1) Are they all independent  and random?

2) When a digit hits, does this increase the probability of it hitting again?

3) When a digit hits, does this decrease the probability of it hitting again?

There are good and valid reasons on all sides. For example one could use the idea that 62% of the draws contain one digit from the draw before to validate the idea that those balls have a greater chance of hitting. On the other hand, that doesn't mean it is going to ber the first number. And don't forget each digit will hit on average every third draw.

So how do you see it?

The program I used is a personal ditty I've used for years. It is simple so I can add a few lines to get a fast answer.

Afternoon garyo1954,

1) Since PowerBall, Mega Millions, and the Texas Lottery use some sort of "ball" machines and not "RGN" programs, then yes, I believe that each draw is independent and random.

2) and 3) Based on answer 1), I don't see how it could "increase" OR decrease the probability if the draws are truly random.

Therefore, is it possible to "track" the historical draw data to get an idea of the ball positions as they've hit in the past. Yes, the draws are random, but...., is there a way to track the hit positions in a column for each draw thereby producing a "probability" for each number based on the historical position hits? Some sort of formula/Vba that could track positions would probably produce a better chance on a "RGN" style game because with enough draws, it may be able to see the patterns produced in an "RGN" program.

Your correct, this subject is definitely for a "gambling theorist", and once this could be figured out, a very good programmer... (of which I'm not either).

Thank you for the lively discussion. It provides me with different ideas to search for and to think about.

I am a big fan of historical data. I tend to use it mostly as a baseline while tracking recent trends.

I might have something that would help. I post it later this evening when I get a chance to find the program and do an update.

Afternoon garyo1954,

That's what I'm attempting to figure out, "trends". How to construct formulas or subs/scripts for... "trends" in the data.

Anything can be counted, but what good is having all this historical data if you don't know how to put it all together and analyze it properly?

Thank you. KH

Can't find the stuff on this machine.

But this is along the idea:

Top part is the overall breakdown of repeating digits - First digit repeats back to first position 285 times, it moves to the second position 240, and moves to the third 234. Reads the same for the second and third digits.

Bottom of the chart shows how many times the digit in each position remains the same, goes lower, or goes higher. But you might be better served to use a chart like this that shows the change on a draw to draw basis.

I don't know. Maybe (hint-hint) WIN D has an idea??

You are dealing with random here.  You are leaving the world of probabilities.  There is no mathematical proof of anything while you are vacationing in the realm of random.  Therefore, anything you may think or say can not be proven nor disproven.

Having said this, you must make decisions as you see them.  Does a drawn number have a better chance of being drawn in the next drawing or less of a chance?  Makes no difference.  You must make a determination and then stick with it.

If the last 5 numbers drawn resulted in an odd sum, will the next drawing result in an even sum?  Again, makes no difference.  You must make a determination and then stick with it.

As for me, I see no advantage in determining trends.  Trends come and go.  That's why they are called trends.  Usually if you have enough data to indicate a trend, you also have enough time passed to neutralize that trend.  I have made my decision and I am sticking to it.

Hello, knuckl, so you can use 0,1,2,3 = high   Average = 4.5 6,7,8,9 = high,   To sort the endings, ok! The big problem as gasmu speak, are the trends and repetitions of a result to another, because one is projected to result, (single event), making impossible any prediction for the whole of the draw, since half if you can predict, for example a lotto 49/6 3-4 numbers can be predicted with confidence, then we have to tackle is the prediction of half of a lottery,   The other part is random, a lottery can see example 49/6 a 100 playing cards, you hit numbers 3-4 pretty easy, this is the way

Evening all,

Reading the last 2 posts, I have to admit that I understand that the draws are "random". I track the Texas, Power-Ball, and Mega Millions games. I've watched the videos of the balls come out of the ball machines. But, without enough historical data to analyze, it appears that specific balls react differently based on the historical data. That's what I'm attempting to figure out how to analyze. Just because a table contains ball numbers with their associated draw numbers in it for a specific time period doesn't mean that those calculations by themselves are enough data to feel confident on the next drawn numbers. My experience has shown me that my data is incomplete and needs different and more intense analyzation.

That's what this post is all about... Understanding different types of analyzation concepts.

So, if anyone is interested/willing to share/discuss some of their different ideas with a "non-math geek" and a very "inexperienced" VBA creator, I'd be more than willing to attempt to comprehend/understand new ideas...

Thanks to all that have replied and to those that have taken the time to read this post. Hopefully, new ideas can be created...

You have ten digits there. Your probability is 1/10.

If you play pick 3 you are likely to lose half of your money.

What is random?

I don't play pick 3, the payout is low.
-1 +500 = 499 with odds 1:1000
499*0.001=0.499

You lose 0.501 of your bet.

Hello SergeM,

Your statement of: "I don't play pick 3, the payout is low.", is very understandable.

It would appear that from your point of view, "low pay out" games are a waste of time. This is also understandable.

From my point of view, attempting to comprehend different theories of probabilities and combinations, then attempting to figure out how to create the program language to implement an idea, it's much easier to work with a smaller number pool. That being stated, I still attempt to apply what I've learned with the Pick 3 game to the other games I track. Sometimes it works, sometimes it doesn't...

But here's the difference, if my strange theories pan out, it's a little money in the pocket instead of no money in the pocket.

Which is more valuable, an empty pocket or a little in the pocket while you continue to test different theories?

I thank you very much for your reply, it's showing me that there's still interest in this post and that has got members thinking... This is good... Thank you.

I analysed some of pick 3 and noticed that if things would go well, you would pay a lot of tickets and you would get just a bit over break even. If the case doesn't come out, you lose big money.

The only interest that I had in pick 3 is working out odds and tables in Excel.

Again, if I consider that you could win a pick 3 by some method, get break even consistently, then you might double your money at roulette. That I would do!

Technical problems like wheeling can be solved. Printing on the tickets is also possible, if you can handle the settings and the stinky printer.

The main part is the picking of the numbers and getting a payout that is higher than all the money that you put into the tickets. If you have a sure way to win, I gather the cash to play. For pick 3, for a dollar input, you would need to win a bit more than three times in thousand to make 50% net winnings.
The more you spend, the more you must win.

I might work out probabilities, but I really don't believe in that one.
