Unformatted text preview: integrating R (1(1ex ) n ) dx by parts. 4.2.7 E ( 1 X + 1 ) = X n =0 1 n + 1 e n n ! = e 1 X n =0 n +1 ( n + 1)! = e 1 ( e 1) 4.2.8 The generating function of X is r ( z ) = X n =1 z n (1p ) n1 p = pz 1z (1p ) . Then EX = r ( z ) = p (1z + zp )pz (1 + p ) (1z + zp ) 2  z =1 = 1 /p....
