Three Paradoxes

Actually yes. I was recently curious about determining a comparitive probability of being seen by a zombie indoors as out and musing that montey might involve himself in the problem. I understand If you are where the zombies are your more likely to be seen. But without a knowledge of the distribution of zombies one should be able to deduce if it is for instance 4 times more likely or 10 time more likely or no more likely at all to be seen outdoors from a generic Malton wide perspective.

Does your remaining still or choosing to move have an effect the probability or is it solely dependent on the zombie (observer)?

As probability is all about events/outcomes would your choices multiply/add into this or only the zombies choices?
