Two random walkers and walk on a one-dimensional lattice. The length of each step taken by is one, while the same for B is two, however, both move towards right or left with equal probability. If they start at the same point, the probability that they meet after 4 steps, is
- 19/64
- 25/32
- 311/64
- 43/16
