Question

Assume that the random variables x 1 , . . . , x n are independent and binary {-1, 1}-valued with p { x i = 1 } = p i and that f : { 1, 1 } n r has the bounded differences property with constants c 1 , . . . , c n . Show that if z = f ( x 1 , . . . , x n ) , n var ( z ) c 2 i p i ( 1 p i )
