Further observation:
On Saturday 20th Nov there were 40 winners of Match 5, each receiving just over €1,500. The numbers drawn were 9,14,22,32,38,42
On Saturday 6th Nov there were 120 winners of Match 5, each receiving just over €500. The numbers drawn were 5,6,9,15,19,25
And the pattern is repeated for the lower prizes.
We see here the "birthday" effect. The earlier draw could have come from all birthdays, not so the later draw. There is also the factor that original Lotto fans will have stuck to a selection of numbers which in those days had to come from 1 to 36.
The message is that you greatly reduce your expected individual* pay-out ratio by sticking to numbers 36 and under and vice versa. But the ploy of sticking to numbers in excess of 36 would also probably backfire as there only need to be about 1% smart asses doing that to counter the birthday syndrome. In a similar way the numbers 1,2,3,4,5,6 have every bit as much chance as any other selection but there only needs to be 1 in a 1,000 too smart for themselves asses to negate any advantage.
Probably best to pick 3 numbers in excess of 36. Off the top of my head I would say that this would push your expected pay-out ratio up to over 150% in current circumstances.
* the aggregate pay-out ratio is unaffected but because of sharing the individual pay-out is diluted
Thanks for this Duke. It's a good read. Just to summarise, you are suggesting cashing in all my investments, play the lotto while making sure that I pick 3 numbers over 36 and I am guaranteed to win €19m. That's my understanding anyway.....
Not quite. Say you now enter Wednesday's draw. Your expected return is +50% per 2 days or something astronomical p.a. That surely beats what you expect on your investments.
BUT you run an enormous risk. For say even €100,000 worth of tickets my guess is that you are well odds on to lose over €30k (that's finger in the air, I haven't run the numbers), but a slight chance of winning €19m. Would you be happy with that risk/reward trade off?
Of course you could try covering the lot. Four problems with that. Firstly you will now have to cover the birthday numbers as well so your expected returns are down to +30% over 2 days. Secondly, there is a chance that you might have to share the €19m jackpot. Thirdly, do you have €21.5m to invest? Finally, try buying 10.7 million tickets between now and tomorrow's draw. And there is no point in starting now for Saturday as tomorrow could see the party over.

While the discussion on the expected return is amusing I think there is a potentially very useful point on the relationship between risk and return.Not quite. Say you now enter Wednesday's draw.

Incredibly 531 chose 1,2,3,4,5,6 . I guessed that there would be people who realising that this combination had the same chance as any other but would be the unlikely choice of a typical player and would therefore think they were unlikely to be duplicated. What they didn't realise is that there were 531 duplicates of similar thinking people@Duke of Marmalade
You'll enjoy this. Back in 2014, the jackpot was shared by 6 winners. Image shows what their selection docket would have looked like.
Six Lotto jackpot winners means getting ‘just’ €588,000 each
Winners all choose bizarrely similar pattern on playslip to split more than €3.5mwww.irishtimes.com
A line cost €2. But you can expect a €1 payout in non jackpot prizes. So the overall worth of a line is €1 in non jackpot prizes + €2 in jackpot prizes equals €3 in total, a mark up of 50%. (This ignores a reduction for leakage due to sharing of the jackpot).The expected return on a lotto ticket for the current draw is €2 on a €1 investment. That is you have a 1 in 10 million chance of winning €20 million for a cost of €1, between now and draw time a €1 line is worth €2
I don't think that was what they were thinking. More likely they just didn't understand what they were doing at all.Incredibly 531 chose 1,2,3,4,5,6 .

Yes, that must be the main reason, but I guess there would be a minor element of smart-ass-ery at play.I don't think that was what they were thinking. More likely they just didn't understand what they were doing at all.
I don't think many people fill in the boxes in sequence, but it is true that being higher up on the ballot does make it easier to get higher vote preferences. If I recall, Beverly Cooper Flynn kept the double-barrel name after separating from Mr Cooper!I don't think that was what they were thinking. More likely they just didn't understand what they were doing at all.
On a related note, it's a well know feature of our PR voting system that a good chunk of people vote 1, 2, 3, 4, etc, in alphabetical order, right down the ballot paper. Approximately 1% of the electorate does this. One of the reasons candidates tend to "manipulate" their surnames to get higher up the ballot paper. (Eg, dropping an O' so that O'Carroll becomes Carroll, inventing a creative new surname as Gaeilge, adding a suitable double-barrel etc etc.)
The effect is small but material.it is true that being higher up on the ballot does make it easier to get higher vote preferences
He probably doesn't understand probability.Further trivia. Listening to Joe Duffy on Tuesday (my excuse, I was in the car and the Duchess never misses him). He is going on about the Lotto these days. Some really ill informed commentary including from Joe himself. One in particular had me screaming at the radio. Some guy who works for Google claimed to have won €100,000 this year on the Lotto. I do not doubt him, in fact I think he showed evidence to Joe.
His formula? He backs the various spin offs that are offered by Paddy Power which he claims are far better value (on balance that is correct), but here's the killer, he follows the "form" of the numbers coming up and can predict the higher likelihood numbers in a future draw. Joe seemed to believe him. I kid you not
Too much Carlsberg, probably.He probably doesn't understand probability.
I have done 5 Quick Picks for tonight's draw.
One of the QPs was 3,7,11,13,16,31 which breaks my rule!
Nonetheless my €10 investment is worth about €14 at this moment.
I am accepting bids over €13.
Warning for novice investors: If you ask in a shop for a lotto ticket they will ask you if you want Lotto Plus. You don't. Lotto Plus involves an additional €1 investment which buys you into 2 supplementary draws but these do not benefit from the €19m carried forward jackpot.

As amply demonstrated in other threads, Joe doesn't do any kind of mathematical rigour. On the other hand, if you feel like some uninformed, vapid, mindless and prejudiced emoting, Joe's yer man.He probably doesn't understand probability.
