Would anyone have a suggestion for this math/probability problem, please?

Asked by elm (3points) December 2nd, 2009

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, ⅓,
.49, .499, .501, .51, ⅔, 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)
——————-
My idea is this:
If the amounts are won by winning streaks, then the solving would be raising each p to the 10, 100, and 1000.
But one can win 10 games haltingly: e.g., win seven in a row and lose two in a row, then win five in a row.
And this is in no way possible to tabulate.

What do flutherites say?
Thank you in advance for any input.

Homework, right?

Somebody who takes that in college showed it to me, and I showed to others. Nobody can handle the unlimited credit.
