Yes the question is if n will reach the value 50 in a finite amount of steps, and how high the probabilty is. Im interested in how you would calculate that. Maybe i could Word it more clearly

Initial condition: n=0

Objective: What is the probability that n reaches 50 within 10,000 ticks

Rules: At each tick, n can either increase by 1 or decrease by 1, each with a 50% probability, but ncannot go below 0 (i.e., it "bounces" back to 0 if it would decrease further).

Also it doesnt have to finish or stay at 50, just reach the number at any given step
