Neb. lottery numbers drawn twice in row

it depends on what you are calculating, if they are sayinng any 3 numbers repeating, then the odds are 1 in 1000.

the fact is you dont care what 3 numbers are drawn makes the 1st draw irellevant, say 111 is drawn , who care is could have 222 or 345.

that sets the number you are testing for the second draw, which is 1 in 1000

infact you are stating unity for the test of the 1st draw, the odds of any number being drawn is 1000 in 1000 or 1

so the odds are in fact 1x1000

It happens at least once a year in Maine on the Pick 4 which is even higher odds of happening.

Making it easier to visualize and solve is all well and good, but sometimes it's too easy to simplify part of the answer out of the calculations, and we both did that.

By calculating the chances of getting the same number on the first 3 days without getting it on any of the other 3, you've excluded the chance that it could happen on other days, and still only happen 3 times. Even if we limit ourselves to 3 consecutive days instead of any 3 days, there are still 4 possible outcomes. The 3 cons... [ More ]

This not what I am getting Experimentally.

This comes from actual data taken from the Wisconsin Daily Pick 3 draws.

Below is a short list of the calculation, however, you can download the Excel file with the following link.

It reaffirms the calculation of (1 current known draw / 1000 next unknown possible draws).

I'll go back to what I said earlier. The odds are 1 in 1 million for two draws in a row to hit one number that you pick in advance. For example, if I say that the number 821 will come out in NJ today and tommorrow, the odds are 1 in 1 million that it will come true.

JADELottery — Sat, 31 Jan 2009 14:11:26 GMT

Alright, ONE MORE TIME... the probability that the same exact combination will hit the next draw is 1/1000... PERIOD.

NOT 1/1000000... IT'S 1/1000.

As soon as the draw is made, there are no probabilities to calculate... it's just 1, because it's a KNOWN combination.

Probabilities that calculate numbers like 1/2, 1/10, 1/100 or 1/1000 are for the UNKNOWN.

Hence, because the current draw is KNOWN and next nights draw is UNKNOWN, the probability is 1 x 1/1000 or 1 / 1000.

Yes it is not truly a ball drop so I am not that amazed I mean it happened here in Florida with 3-5-4 last week...to answer your question... they somehow figure that the formula of independent events applies, whereas it really does not because here is why:

If I ROLL A pair of dice, the odds of both the dice being rolled landing 6 is .... 36:1 because the formula is...the odds are calculated as 1/6 x 1/6 = 1/36 (SIX Faces on a die)

It depends how you look at the odds. [semantics]

If you say 'What are the chances that 000 will hit tonight and tomorrow night?', That's 1:1,000,000 (1000*1000).

If you say 'Since 000 *already* hit last night, what are the chances that 000 hits tonight?', That's 1:1000.

If you say 'Since 000 *already* hit last night, what are the chances it will hit for the next 2 days [making 3 in a row]?', That's 1:1,000,000 (1000*1000 since the previous night has no bearing since it has already occu... [ More ]

Fair question. It doesn't have to be three days in a row. It's easier to visualize solve it that way, though.

Here's my work out, for a 6 drawing set. Now, remember I was answering RJOh's question of the odds of a threepeat . He didn't specify a certain number.

Let's call our target number 000. That comes out on the first day.

On the second day, 000 has 1 in 1000 chance of falling again. Overall odds so far: 1/1000

On the third day, 000 has a 1 in 1000 chance of falling again. Overa... [ More ]

When you say the same number exactly 3 times straight do oyu mean 3 days in a row? If the chances of having the same number come up 3 times in a row during a 3 day period is 10.00 in 10 million, wouldn't it be substantially more likely to happen 3 days in a row during a 6 day period? After all, there's only one way it can happen in 3 days, vs 4 ways it could happen over 6 days. For any 3 days in a 6 day period it would be about 1 in 100,000.

They draw 6 times per week. I got 9.96 in 10 million chance of drawing the same number exactly 3 times straight, out of 6 drawings. Just under 1 in 1 million.

LckyLary — Sun, 25 Jan 2009 17:31:47 GMT

The odds of one particular drawing to the next matching is 1 in 1000. The odds of it matching one drawing to the next at some point sometime is almost certain! The odds of *the next two drawings* matching a given drawing i.e. the same Pick-3 3 times STR, is 1 in 1 million. In the slot machine analogy (sorta) maybe they were thinking the odds of 2 specific draws in a row matching a *certain* STR # chosen arbitrarily.

jr-va said A lot has to do with precisely the way the question is asked, which is a good point. I'd say that most people get the chances of the same number coming up twice in a row wrong because they're answering the wrong question.

The chance that any specific 3 digit number will come up in one drawing is 1 in 1000, so the chance of a specific number coming up in two consecutive drawings is 1/1000 * 1/1000, or 1 in 1 million. Since having a drawing means that some number will be drawn, the c... [ More ]

Pick-3 is like a slot machine with three ten number reels.

1:10 x 1:10 x 1:10 = 1:1,000

Think of two slot machines with three ten number reels sitting side by side having the same three number combination come up in the same order.

1:1,000 x 1:1,000 = 1:1,000,000

However, once the first machine has been pulled and we know that combination the odds of the second machine matching it are 1:1,000.

1 x 1:1,000 = 1:1,000

At least that's what I think. BobP

You are right and this should be true for all lotteries.

The average rate of reoccurrence for a draw to repeat itself the next night is once every 1,000 draws.

That's once every 2.738 years.

It's an average only, meaning it's more likely to happen sooner than later.

You can find the distribution of these rates of reoccurrence using a topic we posted a while ago, Discharging Reoccurrence Distribution and a related topic, Random Number Transforms - Reoccurrence Distribution.... [ More ]

jr-va — Sat, 24 Jan 2009 02:43:37 GMT

interesting

on one hand I see that ANY 2 draws have 1,000,000 possible 2-sets because it's 1,000x1,000

However, asking for odds of ANY TWIN of previous draw does seem that you would divide 1,000,000 by 1,000 possible sets of twins ...and it equlas 1:1,000. (So do the odds of having a SPECIFIC TWIN equal 1:1,000 because of having 1,000 possible twins, but it must be a day of twins first) . I am still somewhat confused

That's for any straight three draws in row.

Since all possible straight repeating drawn three times in a row is as follows:

1st - 2nd - 3rd

0 0 0 - 0 0 0 - 0 0 0

0 0 1 - 0 0 1 - 0 0 1

0 0 2 - 0 0 2 - 0 0 2

9 9 7 - 9 9 7 - 9 9 7

9 9 8 - 9 9 8 - 9 9 8

9 9 9 - 9 9 9 - 9 9 9

There are only 1,000 possible ways this can happen.

The total possible ways for any straight is as follows:

1st - 2nd - 3rd

0 0 0 - 0 0 0 - 0 0 0

The Quick Picks generator available by clicking the link on the left uses a regular old RNG. I do make an effort to use constantly-changing seed values, but it is still a regular RNG.

I am in the process of changing that to a much better, cryptographically-advanced RNG, and I'm halfway finished.

In fact, if you use the iPhone/iPod Touch version of Lottery Post today, the quick picks generator in that site uses the new RNG. The Quick Picks generator in the main LP site will eventually look... [ More ]

That makes sense, from the standpoint that in reality it has happened many times in the past.

I think it would be 1 in 1 million if you chose one particular combination in advance, and that combination hit on two consecutive days.

It's not 1 in a million. The probability of the previous night's draw mathing exactly the next night's draw is 1 in 1000. Exactly the same if someone plays one single straight play for that night's draw.

Todd — Fri, 23 Jan 2009 16:03:26 GMT

I personally think when computerized drawings are involved, you can't use regular mathematical odds.

It really depends on what kind of RNG the computer is using.

With computers that use the decay of radioactive material as their basis for the random numbers, then I feel like it is sufficiently random, the odds are probably a good measure. (Although nothing makes me feel that computers should be used for ANY lottery drawing they are too susceptible to hacking or errors, thereby bypassing th... [ More ]

Neb. lottery numbers drawn twice in row

Lottery Post — Fri, 23 Jan 2009 15:27:59 GMT

The odds are against something this odd.

A Nebraska Lottery official says the winning numbers for the state's Pick 3 lottery on Tuesday were exactly the same as the winning combination from the night before.

Lottery spokesman Brian Rockey says one of two lottery computers that randomly generate combinations picked the numbers 1, 9 and 6 in that order for Monday night's drawing. He says the other computer picked the same three numbers Tuesday in the same sequence.
