Hi guys, if X1,X2,...,Xn are independent and identically distributed random variables, how do you find E(max(X1,...,Xn))?
Do you need to do order statistics or anything of that sort here? I got my answer by letting Y=max(X1,...Xn) and I got the CDF and then pdf of Y. For the CDF of Y, I just noted that P(Y<=y) = P(X1<=y, X2<=y,..., Xn<=y). Is this right?
