So in the UK the Euromillions lottery tonight will be £167M. For those outside Europe, a Euromillions ticket consists of 5 numbers (from 1-50) and 2 lucky stars (from 1-12). Jackpot is won if the winning balls match all 5 of your numbers and both stars (5+2). Larger to small prizes are won by matching various smaller combinations of those e.g. 5+1=£200k 5+0=£16k 4+2=£1k ... 2+0=£3
As a syndicate of 10, friends of mine repeatedly end up questioning their approach to choosing numbers. The syndicate buys 10 tickets, with the numbers for each of their tickets chosen individually. Inevitably, some numbers/stars are duplicated across the 10 tickets whilst other numbers don't appear on any of the tickets.
Would it make a difference to the chances of winning something (not necessarily the jackpot) if the syndicate made sure it covered all the numbers 1 to 50 and all the lucky stars 1 - 12 across the 10 tickets.
Yes, the chances of winning something will increase if you cover more numbers, since no matter what the lucky numbers are, you've gotta get them covered. However, the expectation of how much you win will not be improved.
