What probability distribution applies?

  1. Dec 1, 2009 #1
    1. The problem statement, all variables and given/known data

    Peter and Paul bet one dollar each on each game. Each is willing
    to allow the other unlimited credit. Use a calculator to make a
    table showing, to four decimal places, for each of p = 1/10, 1/3,
    .49, .499, .501, .51, 2/3, 9/10 the probabilities that Peter is ever
    ahead by $10, by $100, and by $1000. (p is the probability of Peter winning the game)



    2. Relevant equations

    I don't know.

    3. The attempt at a solution

    I don't know what distribution applies, or how to choose the variables.

    Thank you very much for any help.

    If winning is in streaks of 10, 100, 1000 then each p is raised to those powers.
    But if it is done haltingly (e.g., to win 10 games ahead of Paul, Peter wins 7 in a row, then loses 2, then wins again 5 in a row) how could this be represented?

    Thank you, if anyone still looks here.
