Here is a probability question I came across recently:(adsbygoogle = window.adsbygoogle || []).push({});

If the chance of being hit by a car while crossing the street is 0.1, then what are the chances of being hit by a car after crossing the street 10 times?

Obviously the probability cant be 100% (the sum of the individual probabilities), so I think the answer must be something like the sum of the individual probabilities minus the probability that you get hit by a car on every combination of crossing the street - i.e. it is P(A) + P(B) + P(C) ..... minus a combinatorial expansion of the probabilities of getting hit by a car on multiple street crossings.

Does anyone know the correct answer to this?
