Exercise 3. We are in front of a black urn which contains N balls which are numbered from 1 to N. We don't know N the number of balls but we can draw as many balls as we wish if we put it in the urn before drawing another one. 1. Write the statistical model. 2. How can you guess the value of N with the observed numbers x₁,...,n during the sampling? 3. What is the distribution of the greatest number N== max(X₁,... Xn)? 4. How many balls do you want to draw? Help: you can compute the probability that  = N.the name1
