Statistics question

[Alberto Monteiro]

If I have a large, but truncated, sample of something, 
how can I estimate what is the probability that this
something is bigger than some number?

In numbers: from a random sample { x0[i], i = 1 to n }
I observe the sample x[i] = min(x0[i], Xcut), what is
the probability that x0 is greater than K?
