Question

Two volleyball teams are to play a 2-out-of-3 series, in which they

continue to play until one has won 2 games. Suppose that the home

team wins each game played, independently, with probability 0.7. Let

X denote the number of games played.
(a) What are the possible values of X?

(b) What is the probability distribution of X?​

Answer 1

Let x = number of games played H = Home team wins R=Home team loses (Road team wins) RR (0.3)(0.3) =0.09 RHR (0.3)(0.7)(0.3) =0.063 HRR=0.063 HH - prob =(0.7)(0.7)=0.49 HRH = (0.7)(0.3)(0.7)=0.147 RHH=0.147 For x=2, add the RR & HH
