probability of at least one component failing

I have a problem with the concept of the parameter:
"probability of at least one component failing"
A very short explanation is in the Manual chpter 3 page 83, but my main questions are:
1- To calculate the top event probabilty, why the number of failure should be multiplied by the above parameter divided by the total number of trails.
2. How this parameter (probability of at least one component failing) is calculated? any formulation?
The manual has not presented any clue or reference.
Thank you
