Default Basic statistics question

Out of 192 events, A occurs 6 times. If I ran a test 16 times what's the chance of A occurring in at least 1 test?

Never mind, I think I figured it out. Binomial distribution.

That works. Alternatively, this could be computed as one minus the odds of not hitting five times in a row:

P=1-(186/192)^5
