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 N = Total number of hawks and doves apart from the observer
Then, the required chance for survival is:
0, whenever N is odd
(N+1)^-1, whenever N is even
