(a) An asymmetric CRW with and . The walker starts at 0 and then drifts toward and tends to stay near 10

(b) A symmetric CRW with and . The walker starts at 0 and then it is eventually equally likely to be in each position except a boundary state
Figure 6: Transient probability distribution calculated for two CRWs on . The curve for a given shows the probability that the walker is at position at time .
