: Lotto Probability Question. In a 6 from 45 lotto, how do you work out the probability of getting all 6 lotto numbers if you purchase a system 20 (pick 20 numbers) entry? Total combinations for the 6/45 game: : C(45 taken 6 at a time) = 8,145,060 lotto combinations. : Total combinations of 20 lotto numbers taken 6 at a time: C(20, 6) = 38,760. : The probability to get the 6 lottery winners in the 20-number bloc: : 38,760 / 8,145,060 = 0.48% (less than half a percentage point). : You can expect 6 winners once in 200+ drawings. : As I showed several times, it's best to use WHEEL-6.EXE lotto software with filters. You can also use the WHEEL45.36 system you can find on the download site. You still need to use it in conjunction with PURGE-6.EXE. If you are totally new to this site and my software, you could feel out of luck in the first moment. But after some searching, many pieces will fall in place.
