Hello, would like to derive a length of list of random numbers in which I may find some special sequence of few numbers with some probability. For clearness I give an example: I have two generator of (pseudo) random numbers with same range of numbers, let's say (1-k). First generator give a random sequence of n numbers from range (1-k) and numbers may repiet. The second do the same but sequence of m numbers and m>n. What has to be m and n if I would like to find n in m (anywhere) with probability p?
