Tnx, now I understand. So, here would be good to use geometric distribution.
We should have:
X:G(p)
....(1....2......3...............k.........)
X: (
....(p...q*p...q^2*p.........q^k-1*p....)

(dots are just for alignment xD)

...and q = 1-p

...but, what`s p in my example?

I don`t think we understand each other xD
Let`s say that L is 20cm`s long...in that 20cm we need to place two point that are distant less then 1cm one from another...

2) Two points are randomly selected (M1 and M2) along the line L (L => 1). Determine the probability that the M1M2 <1?

The general solution of the question 2), having in consideration your above description is:

$P (Distance \; between \; M1 M2 < 1) = \frac {2L -1} {L^2}$
