    Lottery probabilities

    Sorry if this isn't advanced enough but I'm unsure.

    Basically:
    BBC - h2g2 - How To Improve Your Chances Of Winning The Lottery

    Is this right? Is it really way better to do it in one week than over your lifetime?

    Sorry again for being so brief.

    Yes! Your odds improve from terrible to slightly less terrible.

    Ever heard of a supermartingale? Sure-shot way to decrease expected losses: don't play at all.

    Hi RLEXP,

    Yes! "statistically speaking"

    Mainly it would be because by playing more at one time,
    you are aiming at the exact same winning combination.

    Let's say the winning numbers were the same every week.
    Then you are aiming at the same target every week and it would
    make sense to keep changing your numbers every week
    if you only bought a few lines.

    But if you bought more tickets every week, with the winning numbers
    being the same every week, you have better and better chances all the time.

    That's equivalent to buying more lines in one week
    as you are aiming to hit the same target with those lines.

    Whereas, buying a small number of lines each week
    and changing your numbers,
    you are trying to hit a constantly moving target,
    as you have a new winning combination to try to match each time.
    Which is why some people choose the same numbers each week,
    hoping that the winning combination will home in on their weekly choice.

    You could buy next week's winning combination this week
    and totally miss out on a win!
