My personal risk assessment strategy is to do something like: if my chance of car accident is 1/450 per year, would I pay one car accident in order to get 450 years of driving? If yes, then I drive. I do this for nearly all my risk assessments and I'm wondering how common it is.

wouldn't it be 50%? Tho ofc this isn't the same as "for every red dot I pick, what is the chance I hit a blue dot if I move x spaces down the line", which is what you're talking about?

But anyway that's not really the point of this; I don't know much about probability but I know it's real fucky and unintuitive; my thought experiment is just to help me personally hit judgment calls and have a consistent way of evaluating risk across decisions.

With a sequence it's easier. Do coin tosses: the chance of one head is 0.5. The chance of two consecutive heads is (head AND head) = (0.5 * 0 5) = 0.5^2 = 0.25. For three consecutive heads it's 0.5^3 = 0.125, etc. Same thing with chances of having n years without an accident.

But I don't need consecutive years.
