What are the odds?

If we're going to do it, lets do it properly. We need passenger figures for each station to work out exact probabilities of a person at any one time, in London, using London Bridge station. Elguapo's personal probability of using that station can't be worked out without further input. Why was he there? How regularly does he use that station. If it was a one off due to another reason then the probability gets more complex. More details please.

For the time he was there, he was using the station daily, as part of his commute.
