Quote: If you are able to have a pairs for strictly 4 drawselections it's not "wonderful pairs with one good number in 4 sessions!"- it's a miracle-but I have my experience and know that probably it das not happen too often or maybe not any (100%) of the pairs is sucsesfull in 4 session.

Why this is a miracle, a pair with a good one number in 4 session?
I calculated in this way with BB:

-use =HYPGEOMDIST(0,2,7,49) in Excel, the probability to hit 0 numbers from 2; 0.732142857, so 73% for a bad results!
- use =BINOMDIST(4,4,0.73,FALSE) for pobablility to repeat for 4 consecutive sessions this bad results; 0.287331552, so 28% to wait 4 sessions and don't obtain any good number for that pair!
- so 100-28=71% to have a GOOD RESULT!

It's not a miracle I think. Any pair has a 71% chance to give us a good number in 4 sessions!

And the chances increase: for 8 sessions 91%, for 16 sessions 99%; so any pair in 16 sessions can give us a good numbers; even so exist pair that grow up 20 draws, but its fall in 1%, very, very bad luck!

What do you think?

Then exist some strategy, we don't need to play any pair! So the chances increase!

Perhaps Ido must begin another tread called 49s? I want to post some pairs with good results for that game and to explain how I obtained its.
