Brett,

If it was working before the failure, one should always assume a single 
failure.  Multiple failures are quite rare and are normally induced by 
some outside force (incorrect power, lightning surge, etc.)

There are instances where one failed component will take out another 
one, but that is rare too if the designer did his job right.

In any case, it is all a matter of probability, but no matter how low 
the probability of a failure is, remember that is calculated on a large 
sample size.  If you have only a single unit, the probability of failure 
for that one unit is either zero percent or it is 100 percent - there is 
just no other way to calculate for a sample size of 1.

73,
