버섯왕국에 '토비병'이라는 끔찍한 병이 돌고 있다.
첫 감염자인 보라돌이가 뚜비, 나나, 뽀와 접촉하고 죽었다.
이 세 접촉자들 중 두 명은 감염된다.
감염되었든 안 감염되었든 접촉된 사람들은 다시 세 명과 접촉을 한다.
하지만 이상하게도 잉클링인 걸과 보이는 감염되지 않는다.
뚜비와 뽀가 감염되어
뚜비는 마지 심슨, 레미와 루이지,
뽀는 로이, 피치, 데이지와 접촉하였고
로이는 걸, 증기기관차 토마스와 프레디, 피치는 요시, 아유미와 동키콩, 데이지는 괴도 키드, 줌마와 마리오와 접촉하였다.
마리오와 루이지가 각각 토비병에 감염될 확률은?
