Guys...please...

My post was not meant to predict the failure of these systems.  I spoke
from a mathematic prospective of probability...you know combinations and
permutations.  If the probability of one thing happening is 1% and the
probability of another is also 1%, the probability of both happening is
1% X 1% or .01%.  Math is an exact science...usually.

Posted for "John F. Herminghaus" <catignano@tele2.it>:

         If the success rate is 99.1% for both items, the probability
that=20
both
will work is .991 X .991 or 98.2%.  To put it in more understandable
terms, if
the failure rate for each of two objects is 33%, it is obvious that the
failure rate of the assembly is not 10,9%.

   Mathematically it is actually 1% X 1% which is .01%
