Well, for example probability to find 1 number in a string with lenght of 6,
you need to calculate it's complement:
Probability for NOT finding 1 number among the 6 is
6
(9/10) = 0.531441. (=53.1441%)
Probability to find it is 1-0.531441 = 46.8559%
You'll need 28..29 numbers in your string to find one number in 95%
of the cases.
Probability to find e.g. substring '53' in string of six numbers,
(if I'm right) is about 6% and you will need string of 300 numbers
to be 95% sure that you'll find it.
