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