The overall availability increases when two components with availability < 100% are connected in parallel. For two components `Foo` and `Bar` connected in parallel, the total availability comes out to be:
```
Availability (Total) = (1 - Availability (Foo)) * (1- Availability (Bar))
Availability (Total) = 1 - (1 - Availability (Foo)) * (1- Availability (Bar))
