What are the chances of meeting a star in the subway? I think there is a probability of 3% to 5%. Because these are all stars, they will be very low-key in front of everyone, and they will also dress up in disguise and will not deliberately let others recognize themselves. Unless these stars are as close to civilians as Chow Yun Fat, everyone will surely see her when they take the subway. His probability should be 70% to 80%, but most stars can meet by subway.
