I'd take that as a math problem with the SLA being the probability of being OK.
In this case we can rely on probability rules to get an overall.
For your first case the probability that App Service (A) and Sql Service (B) are down at the same time is the product of their probability:
P(A)*P(B) = 0.0005 * 0.0005 = 0,00000025
The probability that one of ...
