[理工] [機率]變數變換
1.consider a nonnegative integer valued random variable X
suppose that E[X] = 10 & P(X=0) = 0.1 find E[max(0,X-1)]
2.The random variable X & Y are independent and each is uniformly
distributed in the interval (0,1) .Find the pdf of the random
variable Z = X+Y
=============================================================
1.第一題是要找0或x-1最大的期望值嗎 還是什麼意思?
2.Fz(z) = p(X+Y<z) = 積分範圍要怎麼討論??
