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.

2. Relevant equations

3. The attempt at a solution

I don't know what to apply here. Thank you very much for any help!

What random variable would it be appropriate to define?

Thank you for reply, rochfor.
I don't know what p is referring to. If p is the probability of winning a game, I don't know whose player the p is.

I imagine p is the probability of winning a game. I imagine wherever you got the problem from is a bit more explicit about which player's probability it is.
