plz help me to solve this question. i will be obeliged to you.(thank u).


let x(1),x(2),....x(n) are mutual independent random variable . let U be a function of x(1),x(2).....x(k) and V be a function of x(k+1),x(k+2)....x(n).
  prove that:-
                U and V are independent.

the probablity of getting a head on a single toss of a coin is p.consider that A starts and continues to flip the coin until a tail shows up, at which point B starts flipping. then B similarly continues until A takes over and so on. let P(n,m) be the probablity that A accumulates a total of n heads before B accumulates a total of m heads.
  prove that:-
               P(n,m)= pP(n-1,m)+(1-p)(1-P(m,n))
