Somebody talked about a filter to take out "all odd" combinations. Like 7,9,31,43,45,47 for instance.

They said to do that because "it has never happened before." That intrigued me.

The way I figure it, in a 6/49 lottery, here are this many all odd combinations:

25*24*24*23*23*22 / 6*5*4*3*2*1 = 232760

Since there are 13 million total combinations, there should be an all odd draw result every 60 games or so. Pretty frequent.

Has anybody checked  a draw history of a 6/49, for instance, for the frequency of this happening?

Or is there something wrong with my numbers?

I really dont understand why we all have so  much trouble with the numbers being chosen at random. I mean say that they were'nt , then we would be complaining that the game was fixed.

As far as all odd numbers every 60 games or so. that kind of probability factoring isnt ment for prediction of a random dvent. its kinda like takeing an average or an estimate which wont be any use to someone hopeing to win.

Ohio SuperLottoPlus has had 401 drawings since 07/15/2000.  In 2 drawings all the numbers including the bonus number have been odd and in 3 others, only the first 6 numbers have been odd.

11/29/03    07 15 17 23 29 43  +44
02/22/03    03 11 29 31 37 39  +43
04/27/02    01 11 19 27 29 47  +04
03/06/02    13 17 21 31 35 45  +11
08/11/01    01 03 25 39 41 49  +18

Only one drawings have all 6 numbers even.

07/19/00    08 10 12 22 36 46  +41

I would'nt say "it' has never happened." But as RJOh has shown, it's the least likely to happen.

I play the odds based on past drawings. If it's the least likely to happen, it's also the least likely for me to play.

Great. That really confirms the numbers pretty closely. Looks like my math is right. Perhaps others have numbers from other lotteries. Sure beat the argument to filter 'because it's never happened before.' Thanks for the information.

Now that is an odd comment in the math section, pun intended.

Who talked about choosing numbers? Or using the results for predictions? I was getting help in checking my math.

Thanks....

Nearly right. There are 25 Odd numbers. Number of sixes with all odd we can form from this is 25c6 = 177,100. Number of all possible combinations is
49c6 = 13,983,816. So probability per Draw of an all odd Combination is
25c6/49c6 = .012664. Complement of a Non all odd Combination is .987336.

The occurrence should be around 1 every 79 Draws. Over runs of about a thousand in a Lotto game where there is an equal number of Odd numbers as Even Numbers say 44/6 and the Combination is classified as "Evens" if there are more even numbers than there are odd then the number of "Evens" is almost if not identical to the number of "Odds".

Others track it; I have found nothing useful in it.

(Actually, in the article written by Robert Perkis and which BobP  (remarkable similarity in names there) took great umbrance at me making a comment that I stopped reading where the odds was arrived at by multiplying the total possible combinations by the ball-sets (3) and the changes (2) there was an interesting comment (I skimmed through the rest) about the Florida 6/49 Lotto Drawing on December 7th 1991 which was close to 100,000,000 coming up with 9  11  31  35  39  47)

dragon, I checked the last 1000 drawings of the Pa Cash 5 game with the following results:

All even numbers were drawn 20 times

All odd numbers were drawn 29 times

Only once were all odd or all even drawn in back to back drawings. March 1, and March 2, 2004 all odd numbers were drawn.

Results from the first 296 drawings of the old Pa Super 6 game which was replaced in January 2004 by the Pa Match 6 game. After the first 296 drawings I never updated my data.

All even numbers were drawn 4 times

All odd numbers were drawn 5 times

Forgive me, but I don't understand your notation 25c6. Can you write this longhand so I can reconstruct the calculation and thus my error?

I usually calculate these things with the longhand factorial function.

In general, since I am a stout non-believer in predicatability of lottery numbers, I really don't care usually about what you can exactly DO with this information. I am more interested in the facts, and quantification thereof.  Certainly, I would never recommend to anybody to install a filter that removes all odd or even combinations. A funny way of looking at it is this: How does each little ball know it is odd or even? All it knows it's a ball, and sometimes it is drawn.

I just reviewed Gail Howard's latest book, and I find so many 'logical statements' that appear to be utter nonsense, often related to facts like this one, with all even or all odd numbers. It does bug me that there are authors that profit by selling flat out wrong information. I guess that's the activist in me revolting.

Could you please point out some of her "logical statements that appear to be utter nonsense?"

I have the book in question, third edition 1997, and personally believe it's quite good.

To dragon:

Have you noticed something about the odd and even numbers match?If you know which position must be the odd number and which position is the even number,You can improve your chance of winning small prizes a lot more.

I don't think I've read a word that Gail Howard has written and never seen her interviewed etc. That said I do know she has a very successful business in this field. From BobP I know she was one of the pioneers in wheeling and she has a consistent following which means she is giving people what they want. It's not easy to build up and maintain a successful business- so I admire her.

49c6 or C(49,6) or (49)  all mean the same. 49!/43! x 6!

As no doubt you already know if you want to work it out use the Calculator in your Computer in scientific view which has the Factorial Function.

If you look at my first Post on this forum I pointed out that the numbers just ID the objects so whatever your doing should stand up to scrutiny where you use ID's other than integers. I was not warmly received in putting that point.
