Hi, because of the situation right now i was thinking that when someone need to go out for any reason lets say that this person go out today, tomorrow no, the day after tomorrow yes and so on. How much bigger is the probability of getting sick if that person goes out every day?

I don't know if it's a silly question, but since i don't know much about probability i decided to post it. Also i think that the probability of getting sick one day is changing.
