Let $X_1,ldots, X_n sim U[0, 1]$. Let $Y_n = min_1 leq ileq n X_i$.
Show that $nY_n$ converges in distribution to some random variable $W$ . Find
the distribution of $W$ explicitly.




I know that $$F(W)=P(Wle w)=P(nYnle w)=P(Ynle w/n)=1-(1-w/n)^n$$



But I cannot continue to finish the question.

            Slightly less elementary than the other answer, but I believe that these facts are also useful to know. I'll give the outline of the proof, necessary steps aren't that hard to do:



            1) If $ X_i sim U(0, 1)$ and iid, then $min X_i sim B(1, n)$, which is Beta random variable.



            2) It can be shown using convergence of moments that $n B(1,n) rightarrow G(1, 1)$, where $G(alpha, beta)$ is Gamma random variable.
