<PRE><B>Question 76798</B>
The information you have provided allows you to calculate 
the probability of getting the $25 because of a failure 
in less than 5000 hrs.  That probability is 0.03707
So you can expect to get 0.03707*25=$0.9268
BUT you did not post the money gain or loss associated 
with other failure times. So its not possible to answer 
your question.
You can figure out the probability of the failure occuring
at 10,000 or more hours; that would be 0.0000000423667, but
if there is no gain or loss associated with that you cannot
calculate the expected gain or loss.
-------
Also, that last question aboutcontrolling the failures at
1/2 of 1% is a mystery based on the information you have posted. 
Hope this helps.
