Riddle:

You live in Killville - a town populated by 10 killers and 10
pacifists.

When a pacifist meets a pacifist, nothing happens.
When a pacifist meets a killer, the pacifist is killed.
When two killers meet, both die.

Assume meetings always occur between exactly two persons
and the pairs involved are completely random.

Are your odds of survival better if you are a killer? or a pacifist?
Or does it matter?

============================================
Use the same senario, but now start with 11 killers and 11 pacifists.
