Odds of matching from a pool of 21

[ido]

Hi guys,
sorry ,I couldn't post my group last time as I was without internet connection >>>>due to the router got burned through a storm - it was really possible to happen than seems I have to learn switching off the PC in those cases
............
Second me we can do another session of 20 draws ,I'm just
"discovering" an interesting way to exploit the top 10 highest 3rd
skips of the numbers and there is a kind of good long run system.
But...the banking lists must be 2 different in this case.
