  An Anonymous person does not have right and responsibility. And both of them are completely the same. 
  Of course, here is just a fake anonymous field. In the first place, the person is not a person, is an object if he or she is really anonymous, right?

  By the way, I learned about a conditional probability.  It is defined such that: 

A and B is an event.  A probability of A assuming that B happened is called  a conditional probability of A given B and written as P(A|B).

Though, I can't understand it well. Are the original probability space and the one when thinking of a conditional probability the same or not?

　I'm tired, so I finish.
