Consecutive Poisson Distribution

Hey! I've finally learned how to do Poisson Distribution, but hit a road bump in regards to a 'consecutive' event.
For example; If there are a mean of 10 bees appearing in a garden every 30 minutes, What are the chances of 1 Bee occuring for 3 consecutive 10 minute intervals.

To work this out, would this be;

P(X =1)^3
Or, is there a different way to work this out?

Any help is mega appreciated! Thanks

That's right. For your P(X=1)^3 calculation, though, make sure you're using the correct mean number of occurrences (hint, not necessarily what's given). Hope that makes sense!
