Whenever a hawk meets a dove, the dove is killed. Whenever two hawks meet, they fight to death, and both are killed. And if two doves meet, nothing bad happens.

There are H hawks and D doves, and you are either a hawk or a dove. Assuming that meetings are random, what are your chances of survival?

If you're a hawk and H is even, then eventually you'll meet another hawk and die so your chances of survival are zero.

If on the other hand H is odd, you have 1/H chance of survival, as hawks die in pairs.
