If on the basis of a coin toss the world splits, and in one branch I am instantaneously killed while in the other I continue living, there are several possible ways this might be interpreted from the 1st person viewpoint:
```
(a) Pr(I live) = Pr(I die) = 0.5

(b) Pr(I live) = 1, Pr(I die) = 0

```
(c) Pr(I live) = 0, Pr(I die) = 1
```

```
Your example underscores the need for interpreting Pr as a relative concept ( this is my favorite point of view): c) is A observing A. It is seen through the first person A who is killed in one branch and live in another branch. This is called the first person on this list. a) is B observing A: It is seen through a first person B who witnesses the event hapenning to A but lives in both branches. His point of view is called the third person on this list: b) is C observing A. It is seen through a first person C who experiences the complement events of A. He lives when A dies and vice versa. The probability that he will see A live is 0. We do not have a name for this point of view on this list but I could suggest "the complement first person."
```
Thus all answers are correct depending on your relative point of view.
