Hoping someone can tell me the kind of question I'm trying to answer, so I can google how to solve it. For clarity, this is not homework, I'm old and haven't had a homework assignment since the 1980's.

Say there's a 38% chance of me moving out of state in the next 5 years.
Say there's a 27% chance my sister will move out of state in the next 5 years.
Say there's a 4% chance my brother will move out of state in the next 5 years.
Say there's a 2% chance my friend will move out of state in the next 5 years.

I'm trying to answer the question: What's the probability that 1 or more of us will move out of state in the next 5 years? but in order to google an answer, I need to know: What's this kind of probability called? I looked at binomial probability, and it didn't seem to fit...flipping a coin 20 times doesn't fit this problem, because there are different probabilities involved, whereas the proverbial coin is always 50/50.

Thanks for any help
