Each row shows how likely to appear after that exact number of draws, so if you add up the percentages of all the draws before that point you get the cumulative chance (e.g cumulative chance within 4 draws is 25+19+14+9=68% . (i would probably be 72% I f I had the time to do all the pairs).

68% is not 72% perhaps because in the first step you calculated 25% and I thought this:
in the first step I have the formulas:
- =HYPGEOMDIST(1,2,7,49) for one number and must add
- =HYPGEOMDIST(2,2,7,49) for hit 2 numbers and also is a favorable case

so I obtain in first step more than you 0.25+ 0.017857 = 0.267857

and so on in final for step 4 obtain 0.7126 or almost 72%
similarly for step 14 the probability grow up.

In fact this formulas show us a good probability and a pair can play for 16 steps with 99% probabilities!!!

Incredible and even so in this condition is hard to remain with moneys!
Why?
So I saw can exist series of win with length 8-10 and in that time you can acumulate a good amount but even so appear an exception and lost a big part of amount. It's a hard play. Perhaps exist a strategy and a management of stakes, this is what we must discover!
