You live in Killville. Can you stay alive?

Hmmm. This is an ambiguous question I think. I read it originally as surviving one encounter, but it can also be understood to be the "last man standing."

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?

Hi marchawg and welcome to the Den.

Nice job. B))
Can you do this for an odd number of killers?

killers will eliminate themselves after 5 meetings and the only chance for survival of anyone is for one or more pacifists to have not been met by killers before they have elimintated themselves... if the first five meetings are between killers then all pacifists live but once all pacifists die, the killers will still continue until they have elimated each other. If there were an odd number of killers the the final solution would be a single killer to survive... If I wanted to be the survivor I would want to increase my odds by being a pacifist and try to limit my number of meetings in general

Pacifist has better odds at survival.

If you are a killer then you can meet 9 other killers that will kill you and ten pacifists

If you are a pacifist then you can meet 10 killers that will kill you and 9 pacifists

So it is better to be a killer in that town, you have more chances to survive

That's after one encounter. How about after unlimited encounters?
