- Let there be 2k killers, p pacifists. If you choose to be a killer,
- P(survival)=1/(2k+1) by symmetry. If you choose to be a pacifist,
- P(survival)=1/(k+1) since as before we may ignore any interaction
- between a killer and a different pacifist, hence we may pretend
- we are the only pacifist; it's clear now that P=1/(k+1) since
- we survive iff we don't take part in the first k interactions.
