# Probability of multiple occurences over x amount of tries?

As I understand, if probability of event is 3%, over 100 attempts probability of that event occuring is 1 - (0.97^100) = .9524. If that's correct?

Please advise what equation could be used to look at the odds of that event occuring x amount of times (i.e. at least twice) in 100 attempts?

Edit: sorry I'm having as much difficulty explaining as I am wrapping my head around it. These would be independent events each time. 3% chance instance 1, 3% instance 2, and so on. So i.e. how could I consider the odds that that event happened y times over x instances?

Thank you!

That works because the chances of the thing not occurring is 97%. And, if you do it 100 times and they are independent, the chances of it never occurring are $.97^{100}$. So the chances of it happening at least once (which are the chances of it not never occurring) are one minus that.
