There are
49 numbers and 6 balls, so that's 49^6 combinations. Which is 13,841,287,201 (13.8 Billion) combinations.

So at £1 per ticket even if you won the recent £100M Euromillions you'd still have lost £13.7 billion. Even if no-one else won.

Of course, there are also repeated categories in there (i.e. the 13.8Bn includes 123456 and 654321 as seperate combinations). So it's probably closer to a mere few billion combinations. I'd give you a better answer but I'm at work, sorry!

Close
but you aren't predicting all 49 numbers, just 6 of them.

Could explain it but it's already been done better than I could do it here:

123456
Is just as likely to come up as any other set. It's got nothing to do with the numbers printed on the balls, just a combination of six balls at random.

*Edit* I have missed the point somewhat.
