Probability (no idea of the kind, and how to do it)

[elmarsur]

Homework Statement

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.

What random variable would it be appropriate to define?

 

[elmarsur]

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.

 

[rochfor1]

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.
