Good guys and bad guys

You are given a set G of n good guys and a set B of m bad guys. Whenever the a good guy meet a good guy, happiness increase and nothing changes. With probability p the bad guy kills the good guy, if they get in touch (while with probability 1-p, the good guy will survive). If two bad guys meet each other, they will not survive.

Question is: who will survive, and with what probability?
