Just to add to what others have said, I was assuming single no redundancy failure mode. If the product being tested has m-of-n redundancy, things get very complicated very quickly.
In other words, if a shelf of 8 modules can continue to run after 2 of the modules fail, that product has a 6-of-8 redundancy. For topics in redundancy and general reliability calculations, take a careful look at the following NASA website ... http://tkurtz.grc.nasa.gov/srqa/dfr/dfr6.pdf It has some great information.
