What is the coincidence of say a person B coming across another person K, not knowing where the person K is at the time, but just going about a KM from K's residence twice.
multiply to it, the probability of visiting that area in a bus, which traverses in that area for about 20 min.

It must be small. 1 in 250 or 500 perhaps.
