<기자님들께>
앞으로 제 문제는 수학동아에 절대 올리지 말아주세요!
귀뚜라미중 1/100의 확률로 황금귀뚜라미가 생긴다.
귀뚜라미는 2마리씩 무리지어 생활한다
하루가 지나서 짝이 잡아먹히면 짝을 바꾼다.
포식자들은 그냥귀뚜라미만 있으면 둘 다 먹고
그냥 귀뚜라미와 황금 귀뚜라미가 있으면 황금귀뚜라미를 먹는다.
황금귀뚜라미만 있으면 둘 중 하나만 먹는다.
그냥 귀뚜라미가 9900마리이고 황금귀뚜라미가 100마리일때,
어떻게 짝지어야 3일 후에도 살아남는 귀뚜라미가 가장 많을까?(단 어떤 무리이든 천적을 만날 확률은 50%로 같으며, 자연사하지 않는다.)
