Elaborating on the hint: suppose for example the two buses were such that the northbound bus always came exactly at :00, :10, :20 and so on, and the southbound came exactly 2 mins later, at :02, :12, :22 and so on. How often would our two-timer be going north instead of south, given that he comes at random times to the bus station ?
