TL;DR Summary

every sure event like sunrise has probability of one

does the sample space of this kind of sure event contain only one event?

The probability of a sunrise tomorrow is 1.000000.
In general, you would need to be more specific about how you got your number. But in a case like that, "1" will do.

Yes, until that day when the Sun fails to rise.

Yes, until that day when the Sun fails to rise.

And that's when the you need to get into exactly what's in the denominator of your probability calculation. For example, if you made 10,000 perfect copies of the universe and allowed each one to run 24 hours, then you might use sunrise_successes/10,000 as your probability. But you would still have to explain why you didn't get the same result from all 10,000. And, of course, directions to the nearest successful universe would also be handy.
