Keep telling him telling him … if he is going to bet on that sort of foolishness, he may as well bet against that number. The wheel might not be true.


Warning: anecdote alert :naughty2:

When I was a kid in the 70s, when I'd learned how to calculate mean and SD but knew nothing else about statistics and probability, I won £6.23 on the Littlewoods Football Pools using a system similar to this.

My parents used to play with a small stake (2 lines of 8 from 10, I think, which cost about 50p) every week, and I got interested in the form book. Having no interest in football, I calculated the mean number of times and its standard deviation that each number came up as a score draw, and found that the means were all nearly the same, and the SD was very small.

I reckoned that if all the numbers came up nearly the same number of times, if I just picked numbers that hadn't come up, I'd get more and more likely to win. So I persuaded my dad to let me pick the numbers for a season.

Amazingly, I plotted the graph of my score each week, and it did increase fairly steadily, until we won a small payout, which was only a little bit less than the total outlay that season. Given that my dad had never won anything on the pools, he was entertained enough by my success to let me keep the £6.23.

I never did find out what it was about the way the matches were allocated to numbers each week, but it did seem strangely non-random at the time. Once there was a mix of numbers that had come up 0, 1, or 2 times, I found it harder to pick them, and I got bored and stopped, so never became a big winner.

Sorry, I was briefly possessed by the Nostalgia Demon there. As you were.

My father in law has stats going back for the pools, nags and dogs. OK in he is in nineties now, so he has slowed down now; but he has been the same for the forty years I have been married to his daughter. My father in law never became a big winner either.

I avoid that speculation as it might run in the family.

I think if you are averse to speculation, then you test negative for the affliction.

The football pools. Saturday night 6'oclock? (this was 1955) a pint of whelks watching the results around a 14" tele in Putney, London.

We never won anything. My grandfather would put a fiver on the coupon. A lot in those days.

In theory it works. Just always bet enough that if you win, you get all of your money back plus a small profit. But that's why casinos have maximum bets. And as soon as you hit the maximum, the strategy no longer works. It's basically like asking your friend to go double or quits until you win. How many times are they going to agree to it before they see what you're doing and tell you to take a hike?

I don't know the maths of it, but I'd imagine it's not a strategy that leads to a huge profit either, so if you had the sort of money that would allow you to do it, there are probably better ways of making it pay out.

I'm not quite sure what you mean by that. If you place bets at 50/50 odds (which you can't in a casino) then your expected return playing a Martingale over any finite number of bets is 0, your expected return if you have a finite bank roll and play until you win some fixed amount or go bust is 0 and similarly if the house has a limit to bet size your expected return is 0.

If the house has an edge (like all real casino games do) then your expectation is losses.

The important mathematical result relating to Martingales is The Optional Stopping Theorem.

Though betting seems to be very controversial, I still wanna try it. What should I begin with, guys?

It’s probably best if your first experience is a very negative one, so you won’t go for a second one.

Yes.

If he’s young, he can bet his entire fortune. That way, he has time to start over when he loses all of it.

And it’d still probably be cheaper losing it all being young compared to losing steadily playing through life untill old age.

Placing bets can be fun, for sure, but I’d never recommend online casinos. Those places are just entirely designed to make you dependent on your own dopamine thrills. If that’s the goal, then try running instead. Much less risk involved.

I bought a single 1 pound lottery ticket on my 18th birthday... which some may be amused to know is the only time I've ever bet money on anything in my life.

The only sure bet is the one you don't make! :naughty2:

I just read somewhere this morning there are only six states here that don’t have a state lottery. Utah, Alaska, Hawaii, and I can’t remember the others.

I’ve never, ever bought a lottery ticket!

It took me an entire evening of playing a roulette wheel while pretty girls kept bringing gin and tonics to lose my original twenty buck stake, and I left. I’ve spent twenties more foolishly than that evening. I’ve polished enough coins in slot machines in NCO clubs in Korea to blacken my fingers before I learned their lesson: you won’t lose much, but you will lose. Which is foundational to the idea of gambling, I think. You won’t lose much, but you will lose. The institutions (casinos, lottery commissions, etc) wouldn’t and couldn’t exist if it were any other way.

And relies on you remembering the wins while discounting the losses!
